Two seperate suspension noises 88 Turbo II
Hello everyone. I bought a turbo II with 60K miles in fairly good condition. There is a squeak up front and a vibration in the rear. My thinking is the guys that have owned FCs from the low miles on up, have had these symptoms with their FCs and have a good idea what bushing or mount has gone bad.
So the first one in the front, squeaks with hitting bumps in the road and even when idling just not as prominent when idling. And it doesn't do this until you drive around a little, kinda like it has to loosen up first. I can hear the squeak even after I turn the engine off and shake the car. But once it sits for a while, shaking it doesn't produce the sound. With the engine off, shaking the car, it sounds like it's coming from under the drivers side near the back of the engine but closer the the left.
So which bushings seem to go out first in the front and squeak? I'm guessing motor mounts but I don't have any experience with this squeak. I'm hoping and betting someone has.
The second sound is a deep vibration sound when I take off in 1st gear. It sounds like it's in the driver rear wheel well. It makes a burrr kinda of sound only for a second or so when letting off the clutch and the rear end is engaged. It will also make this sound when in the other gears. Say I'm in 2nd or 3rd gear and take it up to 3 or 4 grand in either gear and then let off the gas. It makes the sound then but only for a touch longer and only right after I let off the gas. There's no slack or clunking in the rear, just that vibration sound for a second or so. I replaced the diff fluid with Redline. It kinda sounds like an exhaust shield rubbing and vibrating for just that second. But since it only makes this sound at specific times like I described, I am guessing it's a mount or bushing in the rear diff area. I'm hoping someone has dealt with this sound, can be specific with what parts may have worn out first to give me something to look at or replace first. Thanks for your help.
