2002 4WD front suspension question

  

TxAgs -> 2002 4WD front suspension question (3/28/2008 8:32:57 AM)

Good morning all,

New member here with a quick question.  I have a 2002 Tahoe with 150k miles on it.  I replaced the front shocks about a year ago with the recommended ones from the local AutoZoo.  These shocks did nothing to improve the ride.  Overall the truck drives like a truck, but the front end tends to bounce up and down more than it is to be expected. 

Any thoughts on what to do?  The tires are thick wall truck tires, so they shouldn't be causing much of the bounce.  We are going to start towing a boat and want the shocks sorted out before we do.

Thanks for the help!

Is it lifted at all?

This bounce can sometimes be the result of someone altering the torsion bar tension to raise the front of the vehicle either in an attempt to level the Tahoe or fit larger tires.

This adjustment is called the Z-height, the procedure used to obtain the proper adjustment is a little tedious, I would recommend that you have the front-end re-aligned and make sure that you insist that they correctly set the Z-height prior to aligning the front-end, setting the Z-height is part of a front-end alignment but it is rarely checked and also any adjustment made to the torsion bars requires that the front end be re-aligned.

Thanks guys.

The truck is not raised at all. I think it is probably well worn torsion bars combined with cheap shocks. I'll get new beefy shocks and see how it does then. If it is still bouncing, I'll take it to a shop and get the torsion bars fixed.

thanks again!
