Gearbox Help Needed

[Magik32]

Hey guys,

I need a little help, my gearbox has been making some whining noise pretty much since I brought the car, my car went in for a service the other day, and the guys told me that my problem was the (input shaft bearing) or something. I always thought it was like my thrust bearing, but my old mechanic changed that and it didn't make any difference.

This is all in regards to my Rb20 box from my R32 gts-t.

Is this something that can be replaced??

Is it terminal, i.e like really bad??

Rough costs??

Would I be better of putting a whole new box in??

Thanks is advance for all your helps guys.

Could be the bearings, or could be the gears are scored.

Just keep driving it, if it blows, chuck another 2nd hand one in

Sounds like a bearing...If its making the noise all the time then it has to be a bearing that's always in use...So the input shaft would make sense.

GTR = money pit This is indeed very true!!

Does anyone know if this bearing can be replaced???

And is it hard???

Thanks

I was in a car running the same box and it sounded like it had a straight cut gearbox it was so loud. Mind you it was struggling behind a pretty stout RB25 engine.

Mine started makign a bit of noise so i dumped the Fuchs and replaced it with Castrol and it is now a bit quiter and shifts muc better.

Id be inclined to live with it, turn up the stereo. The cost of running around in circles trying to identify and fix the problem will drive you mad. Do the oil change and keep driving it...RB20 boxes are very cheap 2nd hand, or when it dies you can pull it apart and see if it can be rebuilt.

That said if you can remove it and strip it yourself, then go ahead, but if your paying someone...well:(

What Roy said. If it's only one bearing it's not worth it till it really really really gets noisy as it should do too much damage to the gearbox if it completely blows. I've had bearings completely colapse to the point of ball bearings coming out when I drained the oil and there was no damage to the box. It'll be ok for now.

Brand new gearbox, 100ks later it was making that whining noise. had it pulled apart after 10,000ks, nothing wrong with bearings, but there were score marks all over the input cluster gears!!!

Oh ok fair enough..Wonder what caused that?
