Ok don't laugh too hard, but I've never taken the front of my truck apart and i'm curious if someone who has can tell me if there are bearings in the differential tube?

I've been reading through the FSM and Haynes and I can't tell what is in there.

Thanks in advance!

Differential tube???

limon32

The FSM shows the tube on the long side of the front differential and has it labeled the "differential tube". It also shows a doughnut looking job but doesn't have a label on it. Another picture of the front differential assemly does not show the doughnut thing.

There is no bearing in the axle tube it self, the only thing in the axle tube is an oil seal. There are trunion bearings that hold the knuckles to the axle housing and after that there are the wheel bearing.

I'm not sure I understand what trunion bearings are or where you are describing them being located. Are you talking about the CV assembly on the inboard side?

There appears to be an axle shaft of sorts in the tube, what does it ride on on the outboard side?

Do you have an IFS front suspension ?, I was thinking of my 4Runner that has a solid axle when i wrote this.

Yeah its a 1990 with IFS

IIRC, there was a set of needle bearings in the longside tube of my ADD IFS diff but not in the non-ADD diff

Hmm, ok good to know. I appreciate all the input!

Hey what is IIRC?
