I was out bombing around in my Jeep during the snow last weekend, and it worked great, but once or twice when I was spinning I heard what sounded like a grinding or ratcheting noise, I presume from the driveline. I didn't think much of it, but last night I was pulling a mercedes down the road to bump start it, and I heard the noise again when I put it under real load. That time it was in 2wd. It's a 98 sport, ax-15, NP231, 147k on it (for all you americans), 8.25 rear end, factory limited slip, 235s and saggy rear springs on it right now. I'm hoping you guys can tell me what this sound is coming from, if I need to worry about it or not. As a broke high school student, I can't afford to be replacing things that aren't the problem, if you know what I mean Thanks in advance

 

Keep it simple. Check the ujoints.

 

Rear u joints I agree check em lol common wear part

 

Thanks, I'll take a look
