J30 lsd bushing issues

[ss82480]

Ok so I got a J30 diff out of a 97 and just a couple of days after getting it installed one of the bushings went out. Apparently it got dried out while sitting at the salvage yard. Anyways I was wondering if this has happened to anyone else and what the best solution is? Infiniti was wanting $80+ per bushing... btw this is on a 92. Any vendors make polyurethane bushings?

I believe SPL sells some over priced solid bushings. Or you could swap the guts into a open diff.

Use the bushings from your original differential if they are OK, otherwise get new ones for a 240SX from a Nissan dealer.

ttthave you resolved this? I have the same problem. For now I use the stacked washer trick as the bushing. But I want to get some oem bushing or poly bushing

nissan told me they don't sell them. I haven't called infiniti yet

Yeah I just used the bolts/washers from the s14 diff and solid mounted it to the car. Haven't had any problems.

I used some poly bushings for a Z32 diff and a couple large washers and it worked fine. You have to remove that metal guide that holds the original J30 rubber bushing and then install the poly Z32 bushing.

do you have any part number or brand?
