Help...Clicking/Grinding noise in first and second gear!!! I have a 92 Toy pickup EXT. 6cyl 5spd, and its on 37's. I have a grinding noise coming from what sounds like the transmission or maybe even the driveshaft (binding maybe). Whenever I am in 1st or second gear and am running up a hill or putting a good amound of load on it, it feels like a slight slip and grinding/or maybe binding at the same time. I thought it was the tranny at first b/c it has 170k on it, but then I narrowed it down to what looked like the rear driveshaft or even rearend. it is really pissing me off and I want to find out what it is. I just bought a new driveshaft bearing support b/c the old one was worn out. Someone please help me..im going to go crazy if I dont figure out what it is
Could it be the front driveshaft hitting the crossmember? Pull the rear shaft out and try driving with the front only to see if it eliminates the noise(to see if it is indeed the rear shaft itself). Have you greased the ujoints lately?
I have the same kind of thing and all i can figure on mine is that my motor mounts are bad and under large loads the motor moves over and the header hits the frame. I dont know your exhaust is that close but gives you something to look at.
When I was IFS with a 4" Pro-Crap II lift and 33" tires I went through three of those in a year and that was with proper D-shaft angle and the bearing lowered. The first one I got from NAPA and it lasted 2-3 weeks. So I did what every wantabe rockcrawler does, SAS, Marlin Duals and a one piece D-shaft. Oh, and by the way, same symptoms, growling, clicking, and some times it would fart, at least when it did that, that is what I told T!!!! :grinpimp:
I took a hard look at my driveshaft today and figured a couple of things. I need to lower the bearing...but how much???? And my pinion angle is off just a bit, i am going to take out the blocks, and add shackles and shims to get the right angle...It should be pointing directly at the bearing, right?
