I bought mine just a few months ago as well. I would notice during tight turns (parking lots, u-turns...) That it would lock resulting in a one wheel peel. It wasn't consistent and would only happen every now and then, but I noticed it within just a few days after I bought it. When I'm on pavement I can control my inner child pretty well! Lol but off road my restraint is off the table! I have to assume it was damaged or abused before I bought it.
Hello all! I have a 2002 Chevy Silverado 1500 4x4 Z71. A few days ago the differential started acting up. Its is a Gov-loc G80 with a 3.73 ratio. I decided before taking it to a shop and having them tell me I was in for several hundred dollar repair I would try changing the fluid first to see if that would fix my problem. I took the cover off the diff and took a look at the gears. The first thing I see is the magnet is completely covered with small shavings and I can see chips out of the spider gears. What I thought was the differential sticking in the locked position was the spider gears binding against each other then releasing with a bang. Looks like I'm in for a several hundred dollar repair (or more) after all. So now I know I'm going to have to replace the diff. I need to know what my options are. My truck is my daily driver. I also take it up north on the weekends exploring back lakes along ATV trails that can get fairly rough. Obviously traction will vary from gravel, mud, chunk rock etc... Currently in just on stock size tires but plan on getting a set of 33 inch all terrains for a little extra clearance. I don't think I want another factory G80. I like the look of the Eaton Trutrac diffs and may likely go that route. Are there any other better options for what I am using the truck for? Thanks!
I have some additional info. I'm pretty sure its coming from the rear differential. I've been able to replicate the noise. It does it when making a left turn at slow speeds. Seems the limited slip is engaged and is sticking, disengaging with a bang. I think I'm going to try changing the diff fluid and hopefully that will remedy the problem.
I've started to notice a clunking noise coming from under the bed somewhere. It will only clunk once until I reverse the truck and then start driving forward again, but not as soon as I being driving forward. Usually with in the first 10 to 20 seconds after I being driving forward. Doesn't seem to matter if I'm accelerating hard or going easy on it. Its a clunk you can feel. Any ideas?
Hello my name is Joel and I just wanted to introduce myself. I recently purchased a 2002 Silverado Z71 and came across the forum while looking for info on my new (to me) truck. I've been without a truck for a couple years and I've really missed not having one. So I'm happy to be in a truck again. I've been researching some mods. Looking into programmers, exhaust and adding a leaf to help with the rear sag my truck has. Also need to figure out how to deal with the torque management. Seems to have some lag from a stop and low rpms. Any way just wanted to say "hey"! I'll go back to the search function now!
