Gtr Front Diff- Drive Pinion Play

[jeffworld2]

My GTR front diff has a lot of play on the back (companion flange) and i am worried it is quite rooted. it can move a good 8-10mm to one side only. I'm assuming the bearing pack has had it?

It seems to operate ok but i have developed a new noise matching wheel speed not engine speed and i guesselated. i can't actually tell if the noise is from front or rear though.

My question is can the drive pinion be removed in car or should i rip the engine out. Either i would take it to a diff place and get it done in car or pull it out and swap sumps. I am capable of doing almost anything myself mechanically but have no experience with diffs.

Having formerly been a circuit car there is a lot less under the plenum than most which is why i think it could be done in car having looked at the workshop manual, however i don't know how to get parts etc. so would rather hand this one over lol.

Can be done in car, we do them all the time like that

That is excellent. Too bad you aren't in Sydney. I will have to ring around

Fantastic if i don't need to pull it out again

The hardest part is knocking the bearing races in straight and then setting preload. I highly recommend freezing the races over night or over 2 nights so they go in easily and make sure you give the inside of the housing a light rub with sand paper to ensure no heated metal has raised or moved in the last 20 years. Don't take too much away though
