What did you do with your Tundra or Sequoia this weekend? (8 Viewers)

I'm thinking he may also have spent a side part of nearly an entire career designing the needle bearings in the front diffs - how on earth did that design last for something like 40 years and multiple generations of TSBs and replacements when a cheaper bushing would work better?

That's the only thing I've "fixed" on my Tundra. And I don't think it was really an issue at all. Just a noise. It seems to me it would have happily made that noise for the life of the truck. My truck made that noise from the second I drove it off the lot (I didn't think anything of it on the test drive). For 60k miles.

I removed the needle bearing, and there was zero wear on it or on the CV axle or the diff housing. It just had the tiniest bit of slop that allowed the CV axle to move a couple millimeters in it, which would cause the groaning noise at certain speeds in 2Hi only.

I think that's why they never fixed it. Just speculation.
