how do i replace the front end bushings on 1997 Tahoe
Front Wheel Drive, could be bad CV Joints, Could be Control arm Bushings...
worn front end bushings, the death wobble usually needs track bar bushings but I recommend replacing them all with nylon when you do it.
Your a arm bushings need replaced.
change the sway bar rubber bushings and sway bar link bushings
yes, this is a very common thing. the proper term is front thrust rod bushings, they wear out, the way to tell if they wear out is if going slow and you step on the brake you should feel the steering wheel jump up and down slightly, the car overall should feel loose in the front end when pressing the brake suddenly. the only way to fix this is to replace the bushings, good luck.
Sway bar bushings
Check the shocks first they will squeak pretty bad when going out ( dried out seals ). Bushings will squeak but they would have to be pretty bad to do it when just pushing on the front end.
They do not have grease fittings on the factory bushings or end links but after market greaseable polyurethane bushings and end links are out there at your local auto supply or Off Road store. The soft bushings and non grease end links that are installed from the factory are a bit too soft anyway and should be changed out. www.trailvoy.com - all the answers for your Trailblazer from true enthusiasts!
Check lower control arm bushings.
Possibly the sway bar bushings?
They need to be pressed out and new bushings need to be pressed in. You may use a ball joint press and be creative, you can use a socket if there is no adapter that fits. You should get an alignment after finished, ensure front end is tight.
