We have a '94 Astro van purchased last fall with 68K miles on it. From the very beginning, it would suddenly start vibrating at highway speeds then stop vibrating and then start again for no apparent reason. We had U-Joints replaced, alignments done, new shocks to no avail. Then, we took it to Aamco in Danbury, CT. LOVE THESE GUYS!!! They started scratching their heads and it seemed to us that they really enjoyed the challenge of figuring out the problem and cared about correcting it. They took out the drive shaft and had it balanced. That wasn't the problem though. They serviced the engine. That wasn't it. Finally, they talked to several GMC techs and low and behold, it was the rear wheel wells. One would not immediately suspect the rear wheels to cause front end vibration, but that was the answer.

If anyone else encounters this problem, please save yourself time and money and replace rear wheel wells first.

You can replace the full race freeze plugs and high performance mud flaps and get the same results as replacing the rear wheel wells. :-)

We don't have those on our vehicle.

It was a joke. :-) Seriously. Did you mean wheel wells. The body parts or what?

I gotta agree with corndog....wheel wells?? Wheels....makes a bit more sense.

I guess there's a reason why I'm called dablonde. I was only repeating what my husband had said. He's really the one that screwed it up though. I looked on the repair manifest and it was the rear wheel DRUMS. Sorry guys!!

Leeann94astro

Now that makes more sense

dablonde

At least I can laugh at myself.

Leeann94astro

Better yet - you can laugh at your hubby

Corndog Man

That makes sense. I was thinking wheel weights maybe for ballancing the tires. Drums do ned to be in balance.

Take care.

I should have known better. He's always getting the names of things screwed up. I'm surprised he gets my name right. Oh no you don't - don't even go there!
