Question about 1999 Chevrolet Silverado 1500

2 Answers

Clunking noise when shifting, but not always. It happens on hard acceleration AND low acceleration. I have had the rear end completely gone through. Replaced rear differential. Mechanic said it was sloppy. Some of the clunking noise is gone now, but I still have some. Seems to be coming from front end. Also when coming to a stop the truck seems to rock forward after a complete stop (nose dip)more than usual. I dont think it's the supension. It almost feels as something is loose. After I take my foot off the brake there is a slight noise. Thanks for the help! -gotpmac

    I forgot to mention it is 4-wheel drive and it has 148000 miles on it.

    I will check the ball joints and transfer case next. Hopefully nothing too expensive!

    i am closing this problem out. Since my truck has 150,000 miles on it I think I will just leave it for now. The steering is fine, the transmission is fine.... so I am leaving it for now.

May seem to be unrelated but, I had a similar problem with my last truck and it wound up being ball joints. It sounds similar, (especially the rocking forward after stop), might be something to check. If you're talking about a 4WD, it could be your transfer case.

Another pos. problem is universal joints. If you grab your drive shaft close to the rear end and wiggle up and down you will be able to see it move it shes bad. Most of the time it is this one at the rear end that you feel during gear shifting if shes bad. Also midship bearing check this the same way if the rubber is torn she will do that too. Becareful under there.

That sounds like play in your rear end, it usually happens to all RWD vehicles at some point in their life, and also, check your U-joints, and tranny fluid. If low on fluid, your trans can slip causing a lag in shift.
