Outer Limits 4x4 Board

Alright guys i am pretty sure my pinion bearing is about to go. but was just interested in a few opinions

3rd and 4th gear under acceleration a high pitch hum vibration through the car take for of the accelerator gone. 1st and 2nd dont seem to be a issue though.

thanks.

edit:better add i have just replaced the diff oil and that was no help.

Uni joints??

yeah i have regreased and give them a bit of a wobble.

Remove rear drive shaft. Put in 4wd. Repeat test.

Hi, is there any movement in the pinion shaft with the tailshaft connected. in other words is there not enough preload on the bearings or perhaps a collapsing bearing...

cheers

just went back and jacked up the rear

i can now turn the tail shaft about 5 to 10 mm before the wheels ingage.

alright anyone know a good place on the west side of melbourne to take it in to get a professional opinion on tail shaft or pinion bearing.

people have before mentioned a place in sunshine but i cant seem to find it

Thats pretty normal.
See if pinion goes up and down.
I would still suspect uni's .
Drop oil and check for metal. Report back with a pic.

yeah did the oil this morning one metal shard stuck on the magnet
no up down movement might turn the tail shaft around one night in the week as it was off for a new clutch but i am 100% it went back on the same way it came off.

what did you require the pic of bazzle?

well dont know why yesterday it didnt move but tonight just jumped under and gave it a good wobble and there is about a couple of mm movment in where the pinion seal is.

so i presume this seals it to be a bearing
