Gearbox Problems

[Fryday13]

Right well my 95 GTS4 seems to be laden with problems but just recently whilst driving along at a non stressing speed of 70k's my car made a slight bang and then started clunking every few metres, Its sort of a metallic clunk that Ive semi narrowed down to the gear box area. having said that i could be wrong, i was wondering if anyone may have a better idea of whats happened or if its happened to them? And whats likely to be involved, getting towed to the garage this weekend for a proper diagnosis but if its something i can avoid thats great. Cheers for your help, and if ive posted this in the wrong forum, my bad

If something went bang and started clunking chances are something gave up the ghost. It's hard to pin point what it could be without seeing it, but if it was in the gearbox, removal of the unit and pulling the cases off to have a look inside is the way atm

Every few metres doesn't sound like gearbox, sounds more like diff.

Have another listen to the rear diff.

Have a look at your front driveshaft - check joint - also your front half shafts.

Points to the people who said diff, aparently the front diff blew up, i legitimately havent been going that hard so gave a stern look to the guy I bought it off, and moved forward to getting it fixed. Seems to turn out that the ratio for my car is different to other skylines, so the diff was harder to track down? Are there any other parts that people know of that are especial of the 1995 GTS4 only? cause if im looking to put it all back together it might pay to search in advance for parts that will be harder to find. cheers guys

Your front diff should be 4.363 or 4.375 whereas most GTRs are 4.1 and Stageas are different again. Front driveshafts are common to all 4wd. Your rear diff will be shared with a few other cars.
