Front Wheels Bouncing When hitting Large bump

[Bill Barnes]

I have a 2005 Yukon XL 4WD 5.3 Flex Fuel. It has 278K miles. It came with the ZW7 Premium Smooth Ride rear suspension. I replaced the original shocks, front and rear, with OEM shocks at 80K miles because they were worn out. At 150K, they were starting to feel a little loose, not controlling bounce as well. I replaced them with the Bilstein 4600s, as Markie has suggested. When you have the ZW7, you have to change the rear coil springs as well as the shocks. Bilstein notes that when ordering the shocks, and they do offer the springs. I highly recommend that you also replace the four rubber spring insulators. The new Bilsteins were superior to the OEM shocks in my opinion. I will replace them with new Bilsteins when the time comes. As you can probably tell, I will still have this vehicle when I can no longer drive. I'm 73 now, so...

"jounce". Darn autocorrect!

Thanks for all the advice from everyone. I didn't respond sooner because I thought this site would email me when I had some feedback. But, here is the deal: I bought the Tahoe new in '04, it is garage keep with 133,000 miles and I want it to last until I'm dead so I'm willing to replace anything to keep it in good shape. I have never done any modifications, pure stock, only thing major I have done is replace the front, left wheel bearing about 6 years ago and replaced the rear main seal about 3 years ago. I bought some shocks online that were suppose to be made for the Tahoe but they did not keep the front tires from bouncing. I tried to order OEM replacement shocks from several GM dealers that were suppose to be OEM replacements but they said they couldn't sell them to me because they could not ship them. I finally ordered the same OEM replacements from Chevy Parts Pros with my VIN number that I was trying to order from the GM dealers, and they came back the next day and said those shocks were not the OEM replacement shocks that would fit my Tahoe and cancelled my order. All I want to do is find a set of OEM replacement shocks that are made for the Tahoe. Specs: 2004 Tahoe, 4wd, LT, Z71, 4:11 running gears, 5.3 Flex fuel. I have kept the oil changed every 3,000 miles, changed the tires again 3 months ago to the same size as the originals, P265/70R17 Goodyear Wranglers. I had a set of these on here before these and it ran great. I think the only thing I need is a set of OEM shocks and bmw parts genuine. Does anyone know what OEM part number I need to order that is made for my Tahoe?
VIN: 1GNEK13Z64R141941 Thanks for any help you can offer.

On a torsion bar Tahoe, the front-end bounce after replacing shocks usually means the torsion bars are too soft or other suspension components are worn. Cranking up the torsion bars will firm the ride, but also check for worn ball joints, bushings, or sway bar links, and ensure you have heavy-duty shocks. Adjusting the torsion bars is the main solution, but addressing worn components is important too.
