have a 97 f150 4x4. ive replaced upper a-arms, bottom ball joints, and cv joints. every time i touch the steering wheel i have this horrible squeak. could it be a pitman arm? ive greased everything underneath the truck and the tie rods are good. thanks for any advice. jeff

 

Based on all of the items you have already replaced. If the noise is still outside he truck then it has to be a steering linkage joint. The idler arm may be the bad guy. If the noise isn't coming from outside (sometimes hard to tell) look at your steering column, dash boot/seal and I/shaft.

Good luck!

 

I had a squealing when i first bought my truck and all i did was buy some rust check and this stuff thats like a liquid grease and sprayed all my bushings and and anywhere that moved and did not have a grease nipple and i have gone 35,000kms without a squeal

 

Little bit of a bump, but.
I had the problem but only when turning left.
Turned out to be wheel bearings.
Something to think about.

 

i had the exact same problem...it was my IDLER ARM and the squeak was awful...cost me $150 bucks at the mechanics
