if it's not suspension? (the shakes)

Delfonso · #1 07-22-2007, 06:49 PM

if my front end is vibrating like there is something loose when i drive over uneven surfaces, and sometimes i hear a clunking, but the alignment shop says everything looks fine? what's the next step? i've been under my car trying to tighten things up and look for the source, but i'm no professional. my transmission was rebuilt earlier this year, and i replaced rotors and pads myself. new tires, balanced wheels, re-aligned, i tightened up the pivot bolt on the calipers, and i'm supposed to take a 14 hour trip up north, but i know this car is supposed to ride a lot smoother than it is.

any suggestions.
thanks.

You should find a really smooth surface and drive over that. Sometimes I think I feel vibrations when I drive over imperfect roads but it usually goes away.

Can you provide any info on the trans rebuild? The people that rebuilt mine failed to fix the AWD and your clunking sound could be related. It could also be a lot of other things. Sometimes I get a clunk when I press the brakes. Sometimes I don't.
Are these symptoms found in corners or just straight lines?

the vibration pretty much occurs all the time, its just more noticeable on uneven surfaces, and it doesn't go away or become worse if i depress the brake pedal. i haven't brought it back to the transmission shop that did my rebuild, but i called them and they claimed that it shouldn't be a problem with the front diff, yet, i'm not sure how much was done to the differential or axels, could this be part of the problem?

I had something similar in my honda. It turned out to be my Shocks. One was fine and one was shot bad.

Hope this helps.

I just got done with my silverado being serviced. I heard clunking and felt vibration in the gas and brake pedals while slowing down, turning, accelerating and going over bumps.
It turns out, my front differential bearings (3) were all shot and I had to get a steering shaft replaced also............Somehow the truck was still driveable because I drove with that for more than 5k miles.

Have your front diff. inspected by a second repair shop.

thanks guys, i guess it's back to the shop to see how my differentials doing, unless there's someway I could test it myself. i'll post when i get it all figured out.
