Brainstorming on the clunk from by diff

[Zbythegods]

Hey fellow Zilvians again,

I have a 95 s14 witha redtop sr20. I have what I believe to either be an open diff or possible a 1.5way. Not entirely sure, I bought the car with it. If anyone could tell me what to look for I could find out and post it. Months ago I noticed when I go a little hard around turns it would pop and clunk which from my understanding is normal for a LSD or equivilent. Now I'm noticing a slight knock from the diff between 70-80 mph as well as pretty serious popping when I turn from a complete stop. So basically unless I clutch super slow and not give it gas turning, it will pop a lot. Does anyone think I just may need to change the gear oil or is this diff a possible goner? Any help would be awesome guys. I can post pics if needed.

best thing to do is to pop her open and see whats going on down there. if its serious be happy you caught it in time.. a diff that basically locks up/jams is scary as hell going even 40 mph

+1 on this.

Some diffs like to clunk at low speed, tight turns but knocking at highway speed aint right. Check out what's going on in there.

Did you check your subframe bushings? Clunk could be that. If its good, and its the diff, lash could be off.

Hmmmm. Listen guys I really do appreciate that. I'm going to check the subrame bushings first. I hope to the gods it is that but knowing my luck it might not be. What I noticed is it does get worse if I hit a bump on the highway...might be the bushings after all. I just hope I can hold the fort down until this weekend lol.

It is kind of sketchy though. I was getting off the exit ramp today taking a right bank at around 70 and the wheel locked up for a split second. Scary shit lol.

Kinda doubt that it could be the subframe bushings if it's clunking at speed.

Well, the one thing that I haven't seen is anything you happened to notice when you GOT UNDER THERE AND LOOKED AT EVERYTHING BEFORE STARTING A THREAd! But seriously, if you have the sound isolated down to the diff area; the problem could very well be obvious... Just sayin' ;)

Check the nuts/bolts holding your axles to the diff... and the DS nuts/bolts... as well as the other mounting points & the bushings. Could just be some slop due to loose/missing hardware... Also verify the axle nuts are securely fastened thru the rear hubs...

Might be a little easier to help if you can tell us for sure what the problem is NOT... Yano?

Yeah you are right Mike, I apologize for not inspecting it first. It started happening on Monday during my work week and I work 7am-midnight during the week. I was hoping to get a few suggestions so I can take it on this weekend and make sure I still have a car to take to work on Monday lol. I definitely appreciate you guys being helpful for sure. I will update the post with what the issue is this weekend if I find out what it is. I'm going to check all the factors you mentioned. Thanks again.
