Hello folks! I have a 2002 Chevy Blazer LS 4x4. Right now, I have about 185, 600 miles on it. I was successful in fixing the typical half-shaft failure with the front axel, and now I'm hooked! I replaced all the brake rotors, calipers, front lines, front wheel hubs, cross joints, rear bumper, battery, and amazingly I got the check engine light to stay off the right way! The Blazer always passes e-check, the 4.3 Vortec seems to run great, and the transmission and transfer case all seem good, and through the push button 4x4. I hate to give this truck up. Wife thinks it will nickel and dime me to death. I don't want a new car payment, and I'm serious. The problem I think I'm having is with the rear end. Seems to be making a jittery movement at 5-10 mph going up a steep paved road, and some occasional vibrations. There was a "clunk" noise for a good while, now I don't hear it anymore....this noise was after I replaced both cross joints in the propeller shaft. Is this a typical problem with these vehicles? To the best of my knowledge, my vehicle was never used to tow trailers around with, if this makes any difference. I would probably be most successful at installing a good, used rear end from a wrecked vehicle than to go inside and do any possible parts replacements, though I'd prefer the latter. What do you all think about this? My Blazer is my daily driver to work, and is a great fit for me in the many different things I can use it for.

Thank you for reading!

When you do add more details as in if issue noticeable in both 2wd and or 4wd. Test for issue going in reverse like backing up a steep drive vs forward up one. Personally not too sure of the phrase “jittery” but yea, just be detailed.
