Dorman axle and bearing install - Parts review

Dorman axle and bearing install - Parts review - 06/08/13 02:10 PM

Most people seem to be afraid of the dorman axle kits. I needed a cheaper option than OEM. I also had a hard time finding any details about them, thats why I am posting this.

I found a 20% off + free SH coupon for Autozone. I got the 630-205 Dorman kits for $99+tax shipped to my door. I needed both sides, so $400+ for OEM was not an option for me.

Each kit came with a bearing, seal, 5 new lugnuts (wrong type for my p71 center caps tho), and the axle with the studs installed. There was also a stamped ring for the ABS, so nothing to swap from the old axles.

Side note - The axles did not have an o-ring where the c-clip goes. I did my homework on this and it is not necessary to reinstall that. It is just there to make the install at the factory easier.

Some reviews online mentioned that the dorman axles do not have a center hub. The ones I got did. The axles looked exactly like the Ford ones I took out of the car. Yes, they were stamped made in India. My only complaint on the axle is that around where the studs were installed there were some metal filings. I found those by cutting my hand on one as I was installing the axle... mad

The bearings were identical to the ones I took out. The side was stamped USA. They were an exacy copy of the OEM Ford ones I removed.

The Dorman seals looked a little different than the Ford ones. Similar design though and I am hoping that they don't leak on me. I will update this thread if they do.

Also here are some details about what my car was doing, in case anyone is still reading...

So, my passenger side axle had been making grinding sounds for a long time. I started to notice it barely making noise a year ago. It got louder over the last few weeks so I knew they were probably done.

Symptoms - Definite noise on passenger side. With the car jacked up there was up and down play in the rear passenger wheel. Driving past a wall with the back window down and you could easily hear that side making noise. There was no change in the noise if I was turning left or right. Some people have said that you might hear it more when changing lanes on the hwy but I never noticed it like that.

When I took out the axle it had about a 1/16in deep groove where the bearing chewed into it. The bearings themselves were also shot. My drivers side axle which was quiet and had no play was also in the early stages of starting to fail. So I decided to just replace both.

I found no play in the carrier/pinion bearings. Hopefully I did not do any damage to them. Most of the metal filings were in the axle tubes and close to the bearings. Time will tell if I am ok there.

For cleaning the metal out of the axle tubes I took the rag + broomstick idea to the next level. I put magnets on the broomstick. Then rolled a microfiber rag on the end so it was flat like a paper towel roll. To hold that in place I wrapped a strip of wire from some romex wiring around the rag. Basically making it a giant bore cleaning brush that I could keep changing out with new rags. I just kept spraying that with brake cleaner. It worked really well and did not take long at all.

My car rides soo much smoother now. My test drive after getting everything together was like driving a different car. I am curious how much this was hurting my mileage. I have been averaging 18-21 with mostly hwy.

I used Mobil 1 75W-90 synthetic. It has the friction modifier in it so I did not add any. Yes, I want the extra 0.5% mpg.

Starting mileage for the Dorman axles is 170,500 miles. Will see how long they last!!

Read the "Rear Axle Shafts" thread for more insights..Also know that in 2005 they changed from 28 spline axles to 32 spline axles..

Actually its 31......but yeah there was a change in 2005. I also think in 2005 some cars got 28 spline while some got 31.

I took a few pics, but none of the new axle parts. I got them from Fedex later in the day and had just enough daylight to get everything back together. I didn't want to stop and snap a bunch of pics.

Yes I think 05 was a changeover year from 28 to 31 spline.

My car already has the 3.55L rear and aluminum DS. Which BTW made replacing my u-joint so much easier. Was my first time realizing how light they really are!

OEM axles are $400 each or for a pair?!

Re: Dorman axle and bearing install - Parts review - 06/10/13 07:58 AM

Holy crap! That's beyond outrageous

For what it's worth, I had a set of custom 31 spline axles made by Moser Engineering for ~350 for the pair. Plus maybe another 30 or so to ship them an old axle to take measurements off of.

Something to consider.

A year ago when I did my bearing job out of curiosity I asked the dealership how much axle shafts were and they quoted me $1200 each...needless to say I laughed...

Re: Dorman axle and bearing install - Parts review - 06/10/13 12:43 PM

That $400+ number came from pricing them off of eBay. I found some OEM axles for about $130 ea eBay

I figured the OEM bearings and seals could be had for about another $100 or so.

Update on how things are doing. Now at 175,000mi

- So far so good! lol

All the parts in the axle are just as quiet as when I installed them. I am starting to track my mileage to and from work. Same route as a year ago with the worn out parts. My last tank average was 22.6 which is better than it was before. But I also used a different station to fill up. So the new parts are helping.

Re: Dorman axle and bearing install - Parts review - 08/30/13 03:15 PM

I just had the exact same failure on the passenger side axle shaft. Autozone wants $250 for a 31 spline, near double price of the 28. Found Dorman 630-413 31 splines on ebay for about $120 shipped from California, so at that price I'm gonna do both.

Why ford choose not to use an inner race on the bearings is beyond me.

Hey Dave, I know the thread is a little old, but how are the Dorman axles holding up?

Yes- inquiring minds want to know!

Re: Dorman axle and bearing install - Parts review - 07/07/14 05:56 PM

They are still quiet. My car has 188,8xx miles on it now. Still no issues with the axles. For the $100/side it has been a good deal.

Getting close to the 20k mile mark for them.

Re: Dorman axle and bearing install - Parts review - 07/07/14 08:25 PM

My passenger side rear was supposedly fixed per recall warranty but when it went bad again I noticed the dude at the shop didnt fix it he just used an offset bearing.
TO fix it, I bought from Rock Auto the Dorman kit 630-214 for $95 delivered.
However being of much ignorance about rear ends I didnt realize the carrier bearing was shot. It all almost ruptured, so I had a shop rebuild around August 2013.
They told me they replaced both shafts regardless.
As of last month I hear the passenger side making noise again.
The shop told me they used higher quality bearings, I forget the brand. I guess those suck too.

Re: Dorman axle and bearing install - Parts review - 07/09/14 02:18 PM

Don't want to hijack your thread but I need rear axles for my 04 CVPI (28 Spline) and RockAuto has them but they come in 3 different lengths (30.38", 34 3/8', and 31 5/8").

How do I know which ones are for my car?

Re: Dorman axle and bearing install - Parts review - 08/03/14 06:04 PM

The dorman failure begins.

I was driving home yesterday and noticed my rear sounded a bit louder than it has been. Jacked the rear up today and I don't feel any up and down play, so the bearings are still ok. But I saw that the drivers rear backing plate was covered in gear oil. So the seal has failed on that side!!

Which is perfect timing, I start working 5 days a week tomorrow and will be driving 60 miles a day...

Now to see how good their warranty service is.

Re: Dorman axle and bearing install - Parts review - 08/03/14 07:31 PM

Autozone is of no help. Have to wait for an email reply from Dorman to find out how to handle it. According to Autozone there is only a 90 day warranty! Even though Dorman products all have a lifetime warranty.

I think it may just be the seal that failed. I do remember they did not look as good as what was on the car, but I used them anyways. The bearings still seems to be solid. I guess I will get a look when I take it all apart to replace the seal. I might remember to take pics this time around.

My fluid level is still good and the leak is not bad, but I will want to get it fixed.

Re: Dorman axle and bearing install - Parts review - 08/04/14 01:34 AM

The brand of seals I used would be Duralast (which is just a name printed on other brand name).

Their was a video on youtube saying Dorman was crap (he took a file to the OEM and then to the dorman). The file-test (not conclusive) showed that dorman used softer metal.


I expect to get my 1AAuto axle tomorrow. I paid 165$ (shipping included), for hopefully a better brand. Their videos online helped me alot and I decided to say "what the hell" and go with it.

Ordered through Ebay for an extra-level of confidence.

I used Dorman to replace the one in my ex's Marauder a few years ago. They barely lasted a year and a half. Never again.

Re: Dorman axle and bearing install - Parts review - 08/04/14 09:39 PM

I will have to keep driving it as is till the weekend. I will pull the axles and see what is going on. Probably on Saturday. I am quite broke at the moment so if I can get a replacement dorman part, that is what will have to go in there for now.

Fingers crossed that it is just the seal!

Dormans reply about Autozone is basically just print out the page that shows the lifetime warranty and shove it in their faces. So that will be my plan and they had better honor it.

Re: Dorman axle and bearing install - Parts review - 08/07/14 09:46 PM

So I out found what the noise I was hearing was. That was not the axle starting to grind away. The plastic cap on my roof came off exposing the 1.5in hole it was covering. That explains the extra noise.


So hopefully its just the seal that went out. I will post an update on Saturday when I have it apart.

Re: Dorman axle and bearing install - Parts review - 08/07/14 10:17 PM

If you have a few extra bucks PLEASE buy name brand seals and bearings(Motorcraft, National, SKF). No Valuecrap or DudLast or the courtesy crap in the kit. You don't want to do this job over again. The Motorcraft seals are really cheap for a pair on ebay if you sort by price. I see a pair for under $12.

Bearings are also extremely delicate. Even dropping a bearing could ruin it. http://www.timken.com/en-us/products/maintdiag/documents/6347.pdf

I saw the YT video - the axle likely failed because of the cheap bearing.

When I was doing a Co-op at a large industrial company, I was bored one day and found a rather large booklet published by Timken about just about every type of bearing failure mode, their causes, and such. Read it cover to cover. That taught me just how delicate bearings in this sort of application really are. I suggest anyone with an interest views the above PDF and does some research on it - it's actually pretty interesting how easily bearings can get screwed up.

Re: Dorman axle and bearing install - Parts review - 08/08/14 02:28 AM

TIMKEN is all I need to say. I found that the OEM brand is TIMKEN. Its lasted 100k. 3x more expensive than DURALAST (Dudlast haha).

Its USA Made. So definite quality!

Re: Dorman axle and bearing install - Parts review - 08/09/14 11:46 PM







Got everything apart today and got to have a look. The wear on the axle and bearing looked fine for 19K miles. Other than being able to see where the bearing is riding on the axle it is nice and smooth. The bearings looked nice as well. (You can see the USA stamp on these. Which is why I felt it was ok to use them.)

I threw a new Timken seal into that slot and put it all back together. The test to see how long these dorman axles and bearings will last continues for now.

Current mileage is now 190,200

Yeah I read another member here was a mechanic at a taxi company. He said about Dorman axles, that the failure rate was high. He always had to replace the Dorman stuff. That was his experience.

Re: Dorman axle and bearing install - Parts review - 08/30/14 02:28 AM

My 1aauto came with Timken Bearings and seals. Only problem is I didn't know until I installed the ones I bought. Now I have a spare bearing and seal. :X
Posted by: PB92

Re: Dorman axle and bearing install - Parts review - 08/30/14 09:47 AM

Hmmm....interesting. Good 1aauto uses Timken bearings & seals. Now just to see how the axle holds up. I looked last year into 1aauto parts, but nobody here had any experience with that brand, so I didn't buy the parts.

Re: Dorman axle and bearing install - Parts review - 12/28/16 09:50 PM

**Update** ... its been a while

Dorman axles are still working at 230K miles now. I changed my diff fluid again a few months ago and things still looked nice. No play around the wheels. The magnet at the bottom of the diff really helps. All of the fluid around it was nice and clean, only the last bit that drained out had any darkness to it. That puts them at 60k miles so far.

Re: Dorman axle and bearing install - Parts review - 06/28/20 11:37 AM

Another long term update on this thread. Still driving this car with these dorman axles. Rolled 300k recently and still no sign that they are going to fail any time soon. I have changed the diff fluid one more time in the last year.

Not sure if this thread had helped anyone but figured it's worth a follow up.

I like seeing threads with follow ups, so thank you! Also good to know that Dorman can make a part that is not a total POS.
