Front driveshaft seal replacement and part number? (1 Viewer)

[westwardCruiser]

I've been watching what I assume to be the dust seal/cover poke it's way farther and farther out of my front driveshaft. I was going to replace the whole thing but was reading the FSM which seems to indicate this can be serviced. But, I can't find the part number. Has anyone done this and know what it is?

I'm in the boat of replacing the entire driveshaft. If you're going to go to the trouble of replacing that seal, might as well do the u-joints while it's out. Then get it rebalanced. By the time you get all of that done you could almost justify just getting a brand new driveshaft which comes ready to install.

I agree

Interesting. I've never seen the seal of forward or rear propeller shaft slide yoke do that!

Hmm, that was my original plan until I found you could replace the seals.

A year ago I pumped a lot of grease into the shafts and I remember it coming out of both seals. Some point along the way this happened, I think I attempted to grease it once since then and realized I had a problem on my hands. It has gotten worse off the last few thousand miles.

I don't drive the 100 much over the winter, but I'm gearing up for a 10k mile road trip this summer, I think you've all convinced me to just replace it.

Is there any reason I should replace the rear at the same time? Or can I just do that at a later point? (doing a lot of other maintenance and parts are adding up)

I've been using this grease Amazon product ASIN B000CQ4DK0If I'm going to the trouble of getting new shafts, is there better grease I should be putting in there?

That grease is okay for slide yokes and SPC lube-able ball joints.

I'd not use it the spiders (universal), wheel or axle bearings and bushing. It states "can be", but it is EP grease (Extreme Pressure). I keep a tube of EP Moly around for SPC ball joints only. I use Mobil 1 chassis grease for all OEM lube points.

Unless working with a really troubling slid yoke. I use the method Toyota changed to, in the 200 series FSM. Lube slide Yoke "just until extension is first observed".

IMO, for the front driveshaft, I'd just pull it and inspect the U-joints for play (and replace seal). That front slip joint hardly moves and hardly gets out of balance. The rear driveshaft takes the grunt of it all.

If you want to spend money, and considering your mileage and upcoming trip, maybe R&R the rear axle seals.
