Alright I’m pretty new to differentials and anything to do with rear ends really so any advice I could get would be much appreciated. Long story short about 2 days after hitting the trails my 97 TJ started having some serious grinding and vibration issues coming from the rear end. I just opened up the cover on my Dana 35 rear axle and found metal shavings in the fluid and also wear marks caused by the opinion (I watched pictures of this). My question is if my grinding and vibration could be coming from this or if I just happened upon a different issue before it actually broke. If that is the case, then I will need to continue searching for the cause for my grinding/vibration. Any ideas on if this would be the cause? Or am I looking for something else. This to me almost seems like it couldn’t be causing me this much vibration but like I said I don’t know about differentials. Thanks!
