Gearbox or diff issues
 

Hi all, I've just bought my second classic uk turbo (I regretted getting rid of the first) and when I bought it I knew there was an issue with either the gearbox or diff. The guy who I bought it off has given me a spare reconditioned gearbox with the car but I drove 200 miles yesterday and it definitely doesn't handle as well as my previous one. The symptoms of the fault are a loud ish whining/whirring all the time. When it's on load it goes away slightly but when I back off its at its loudest. It drives fine other than the noise. He told me it was the upper linkages on the gearbox but I don't really know anything about gearboxes so I thought I'd ask on here to see if anyone has any other thoughts??? Due to the handling I can't make my mind up between the gearbox or diffs! I also noticed a loud knocking when in 4th when accelerating and a friend said its definitely the gearbox but I'm just not convinced :s
Any help would be brilliant!

Uk turbo boxes are like chocolate, they are ****e! Best putting a later box in it with matching rear diff :)

I've had it checked out and I'm having a the spare gearbox put in tomorrow so fingers crossed it'll sort it out!

Im no expert, but i was getting similar symptoms on mine when the transfer box/bearings went.

The car also made a knocking noise on full lock in reverse, sometimes.

If you can get it up on a ramp and get someone to sit in the car and accelerate you should be able to hear if it is coming from the gearbox or the transfer box.

All sorted now. It also needed a new clutch, so they've threw in an exedy uprated one for me so all is good! For now! Thanks for the input
