I am new to the Forum, and am new to Forums all together. I found crownvic.net whilst researching for the car I ended up buying at a state auction. I purchased an 05 P71 with 130,000 miles on it. I have done a preliminary search of the forums and haven't found the issue I think I am having. Any help, insight, or direction would of course be appreciated.

During acceleration or while driving the vehicle I get a whining noise (only when traveling, no noise when idling or revving the engine in park), that sounds like it is coming from the mid to back of the vehicle. At any speed if I let off the throttle the noise dies off instantly. I can only hear it with the windows of the car rolled up. I have no other indications that anything is amiss.

Thanks in advance

It could be something in the rear end going out. Maybe the gears? Does it have a Trac Lok?

These cars do definitely have louder than average torque converters, combine that with the lack of sound deadening in a P71 and its pretty noticeable. That could just be the noise you are hearing, but this kind of thing is hard to "diagnose" over the internet without hearing it.

Thanks for the replies. I have driven it for a little over 600 miles in a week and the sound seems to be constant and non changing. I have noticed nothing out of the ordinary powertrain wise. As it was suggested I am beginning to think it is just nature of the beast.

On another note I am impressed to have gotten over 23mpg on the first full tank I drained.

A few personal touches along with some elbow grease and I think I can turn this diamond in the rough into a nice daily driver.

Is it almost a whistling kind of whine? I was hearing a similar noise for a long time, and a few months later my transmission went out. Maybe no connection, but I don't know.

before just assuming its normal i'd suggest two relatively cheep maintenance jobs that could help, first change the trans filter and fluid (at least whats in the pan) and pull the cover off the Diff and change that fluid. if you see alot of metal particles in either the trans or dif fluid then you'll have a good starting point for finding a possible problem. worth the price of fluids and gaskets IMO

Mine does the same exact thing, take your foot off the throttle and it immediately goes away. I have 135k miles

affirm^^
I'm almost positive that it's normal especially if u have steep rear gears. a 3:55 for instance


and is louder in any case if u have overdrive off
and even cement freeways are going to emphasize the noise
being that the two sounds are almost identical
and the lack of heavy glass such is now in Buicks and these cars need more sound proofing anyway..especially at the rocker panel areas
but alas..their production is over..so
mehsmile
i suspect all is well with ur car
welcome

According to my door sticker and the tag on the axle its a 2.73 RAR. My 98 CVPI didn't make this noise that I can recall but it had a blower and bigger fuel pump so if it did it would have been hard to tell.

Welcome from Mississippi! Isn't it strange for cvpi to have 2.73? I thought most came with 3.55. IDK
