I doubt this would be the same thing, but I had a nice vibration in the rear of my 60 at highway speed. It was the same kind you can feel when the u-joint is worn out, except the PO said that he had that u-joint replaced. When I installed the Lock Right, I also replaced the hardware store bolts that had been used with genuine OEM bolts and nuts. When I dropped the drive shaft I noticed that the pinion nut had never been staked. Curious, I put my fingers on it and discovered that it was only finger tight!!!! I torqued it down proper and staked it, and my vibration went away. In hindsight, that was a broken pinion waiting to happen!

Jeff, I think an FJ60 is supposed to have a crush sleeve as opposed to a staked nut to keep it on and to set the preload. At least from the factory.

My 62 had a stake nut, I thought they all had stake nuts.

I think I'd check the pinion nut even before pulling the diff cover (less messy, and you need to check the nut anyway).

Well I'm no expert on 60s and 62s, but SOR indicates that after 11/84 crush sleeves were used.

See these threads here:

Jeff's is a 1987 so I figured it'd be better to let him know. Better safe than sorry. Don't know what was up with your FJ62.

They all have the slot in the shaft to stake the nut. That keeps the nut from moving, if you bother to stake it. The crush sleeve is a lower cost alternative to a spacer and shims to set the bearing preload. I think the early 60's used shims and the late 60s or 62s went to a crush sleeve.

Two different things though, right? Some have the crush sleeve, others have the shims, but I say all of them should get their nuts staked. Don't quote me on that...

And all I did on the 62 was replace a pinion seal. Was the first time I ever used a seal puller, in fact I still remember Commander Zepp drawing me a picture of what it looks like, so I could pick one up prior to the wheel bearing packing party where I was planning on doing this. I still have that seal puller, it has removed countless dust seals from front hub assemblies, and has doubled as a spatula on more than one occasion. great tool. ok [/hijack], for real this time!

You're right Tim, I would think that all would need the nuts staked. The problem is that on the ones with the crush sleeve, you can overtighten the nut, which crushes the sleeve more, which increases the preload, which can grenade the diff.

Earlier cruisers had the shim and spacer, so you could tighten that thing down as much as you wanted and not change the preload. And then stake the nut.
