14 Tahoe ZW7 suspension

[mikez71]

I recently replaced all four tires and about a month after driving on them, I started to notice a rather severe bounce seemingly coming from the driver's side front. I purchased replacement front shocks on line, installed them, and found little or no improvement from the bounce.

Might check your front wheel balance, maybe some weights fell off?

@WayneY Look at your RPO codes -- is there a G65? If there is, that's what shows that the rear OE shocks were manual self-leveling Nivomats. The ZW7 by itself does not. (From what I've seen here not all ZW7 Premium Smooth Ride SUVs of your year had them.)

Your severe bounce on the front could be caused by not having the front jounce stops contacting the lower control arms at ride height. Check to see their condition. That contact is a fulcrum point in the front suspension.

Here's a picture of a jounce stop NOT contacting the lower control arm, which is NOT what your suspension needs to work correctly.

There were a couple of members with used Nivomats for sale; if you're interested reply to this post and we'll find them for you.

Thanks. Never heard of those. Will check tomorrow when I have access to my Tahoe.

Just found a photo I took years ago of my glove box sticker. There's only one G code, a GU6 that denotes a 3.42 rear axle ratio.
