i have a 2007 Tahoe with 70K on it. Front shocks feel worn out, as I get terrible shaking in the front end over bumps, especially when I am towing. It feels like the wheels are bouncing on the road. I am very mechanically inclined. What's involved in changing the shocks myself, and has Chevy made any upgrades to the stock shock. I've had this problem since I put about 30K on the truck. It originall rode smoothly. I had the dealer check out the front end, and a private shop, as well. Both said that everything looks good, so I assume it's shocks. I don't want to put the same units in, if they are only going to last 30K. Any thoughts ??
Hi, do you have a coil spring over the shock or just the shock alone? They have both depending on what series the truck is. 1500, 2500 etc. Let me know and i can give you the procedure. Thanks, Eric
It's an '07 Tahoe, the new series. There are no 1500/2500, etc. Mine is an LT. Not sure what the configuration is, as it isn't home with me right now. I don't think it uses torsion bars like the previous series.
Here are the two procedures depending on the setup you have.
Shock Absorber Module Bolt (Qty: 2)
Notice: Do not use air powered tools in order to disassemble or assemble any vehicle component. Bolt torques are vital to diagnosis. You can detect bolt torques only when using hand tools. Improper bolt torques can contribute to vehicle repair problems.

If you end up having the type with the coil spring this may be your problem and you may want to consider replacing the coils. Let me know if i can help you further. Please click on accept. Thanks, Eric
When I click on the "shock absorber /spring replacement " link, it tells me I don't have access. Other than the pictires, this isn't much help. If I have the coil over variety, which I believe I do, do i need to compress the spring to get it back in? Will I need an alignment if I remove the tie rod end?
Sorry about the links not working, it happens sometimes, Yes you will have to compress the spring to remove the shock
