Rear end pinion speedy sleeve

[John-T-53]

My pinion seal is leaking, and it leaked right after I changed the seal years ago, so a groove on there is beyond doubt. Now that I'm aware of speedy sleeves from reading up on this site, I was wondering if the correct size speedy sleeve is known for the pinion shaft for a 1/2 ton truck. Could I install the sleeve on the shaft with the differential in the vehicle? My memory is fuzzy from when I pulled that sucker off there long ago, but I recall the pinion flange being splined and coming off the shaft after the nut is removed.

The yoke is splined on the inside. Take the yoke down to your Napa or Auto parts store have them match a speedy sleave to it. and your set Carl

That's the part I forgot about, but that's good news. I'll pull 'er off and get a ride to Napa and get that dang thang sleeved right quick! Maybe I can leave the existing seal in place and it'll work!?

if you are in a position to remove any seal that has run on a irregular surface and has leaked..odds are the lip could have suffered some bad wear and prevent proper seal on a renewed surface (speedy sleeve) for max economy at not having to re-do a job..get a new seal and install with the new sleeve...you may even sleep better at night...

John-I just put a speedi sleeve on the output pinion of my transmission. The seal looked ok, but there was a groove in the pinion. Drove it over 60 miles over the weekend and it looks like the sleeve solved the leakage problem-haven't seen a drop! Mike

When you are ready to re-assemble , put a thin layer of grease on the seal so that you don't have dry seal to metal contact . It could wear out real quick otherwise before the gear oil gets to it .

I called my local Napa store and they'd never heard of speedy sleeves....anybody have a part number or other info/source where I could find one? Might they go by another name? I might take the yoke to my machinist tomorrow and see if he could set me up...

I pulled off the pinion yoke tonight....used my breaker bar for the nut and a gear puller for the flange. That sucker was on there tight! The pinion shaft is quite wobbly without the yoke on there...I assume the yoke, when torqued down, preloads the bearings inside the diff case which tightens everything up like it shoud be?

I also have a new seal ready when I find a sleeve to ensure a leak-free assembly (and a full night's sleep).
