I have a 99 silverado Ext.Cab and i have exessive tire bounce on the right hand rear side. I thought the tires were lumpy but ive rotated them and this still keeps happening. This only happens at high speeds. Around 75MPH. The Steering Wheel also begins to bounce around. Its now to the point were I have to Slow down to correct the Problem but it gets Very Destracting. Also There is alot of Front End bounce. I cant hit a speed bump or dip at more than 10 mph because Ill be In the Passenger Seat from so much bounce. Will lowering the truck with a good kit slove thall of this. Im thinking is the suspension. Not sure.

Please Help.

Shocks control movement, start there first. If the bounce also bounces the bed---the shock may be seized and will soon break or break one of the mounting points.

What tires and how much air are you running in them? And I suppose this is in an empty bed?

That would be a SHOCKing experience. I would be SHOCKed if replacing the SHOCKs didn't fix the problem. I second the vote for SHOCKs...

So you think its shock? LOL. I guess if 3,4or 5 people( I didnt count) say its shocks then its shocks. Would help to get a complete lowering system. Beltech? Ive been wanting to lower my truck but I wanted to find out what was the problem first so i didnt mess it up more. A lowered suspension will also correct the front end problem right?

I vote canootervalve assembly (shocks)

And also lowering your truck will make it handle better but it may also make your ride rougher. The stiffer suspension parts will make the truck ride rougher over bums and uneven pavement. Just a thought if the bums are annoying now they might get worse with the lowering kit.

I would just replace the shocks first. They're very likely the culprit, but if not then changing the entire suspension could cause other problems without fixing the first one.

Most of us with fairly new trucks have found the GM shocks to be sub-par even at low miles. You're probably about five years overdue

OOOOOOOOPPPPPPSSSSS!!!

Please don't test your suspension by running over any bums. Please test it on bumps.

Hey, Guys. After re-reading this, I think we're mis-reading SPL's request here. He appear to be asking for a serious technical argument (wink,wink) to convince his S.O. ("Significant Other") that plunking down the dough for a fully-lowered suspension will solve the problem. So, with that in mind, here's my response:

"Yes definitely, you get my vote! Oh, and you better check into a Westers. I hear that might be necessary to get rid of the "shimmy" in the back after you lower it. Glad I could help!"

Its the tire(s), they are out of balance or out of round.

I agree. Print this to show the SO...

Your problem is serious! Stop driving that truck at once!

Your wheels and tires are screwed up, and you need aftermarket replacements. That alone will not fix the problem though... The ONLY WAY you are going to be able to fix that problem is the wheels and tires AND a complete lowering kit, with a C Notch Kit and Air Bags. Yes, you will need the Westers Tune to re-calibrate for the decrease in height, but it will all be worth it to get rid out that bouncing wheel...

I would also print this out as well to show the SO that the staff here concurs with what the solution is to address your issue.
