8.6 Yoke Sleeve

2000 Suburban 1500 with 10bolt 8.6 rear.

 

I replaced the 3.73 original gears with new 4.10.

- Set correct pinion depth, correct pre-load with all new bearings, crush collar, seals.

- Installed diff., checked backlash, preload, checked gear pattern, everything up to specs.

 

I thought everything was ready to go - until the gear lube ran right out of the new pinion seal!

 

Fortunately, I kept all of the old parts and found a sleeve that I removed from the yoke because it looked pretty warn and had grooves in it from the seal. I just assumed this would be in the rebuild kit.

 

My first question is: should I get a new crush collar and nut and re-set everything after pulling off the yoke and reinstalling.

 

The second is if I can even purchase just this "yoke sleeve". I have not been able to track it down yet. The GM technical manual refers to it as the "pinion flange oil seal" (not to be confused with the pinion oil seal), but the parts manuals do not show this item. The seal has a part number of 26060975 on it.

 

I do not want to use the old one, and I want to avoid having to buy the yoke from GM for about $150 - which may or may not have this seal or sleeve with it.

 

Thanks in advance for your help :sigh:

Thanks all for the help and responses :fume:

 

I did find out that the yoke seal cannot be purchased individually. It can only be obtained with a new yoke kit from GM. This kit includes the yoke with the yoke seal, the pinion seal, and a new nut and washer.

 

The dealer gave me a break on the price and I only paid $99.

This is the first time that I noticed the thread. I bet you would've received more response's, if you would have asked your question in the new member section, along with an introduction about you and your truck. :fume: On another note, welcome aboard.

      I did the new thermostat after doing a 'flip' for a year. Runs as cool one way as the other in the summer but in the winter there is a bit of a floor. Yellow with the new 70 C thermostat. My data over the life of the unit to date. Still need more cooler. Anyway that floor helped both winter fuel economy and shift quality in the winter. I found it a good balance.

      Evan Williams Bottled in Bond   So pouring the last of a bottle of Evan Williams Black label last night I set off the the state store for a refill only to be denied the by an empty shelf. Rats.    What the did have was a bottle of Evan Williams Bottled in Bond. 100 proof. Hum, a few bucks more but a known distiller. Lets have a swing at it. ( I have before )    Cracked it open and pour a serving over ice. Hum.... more heat, yes. More alcohol naturally. But the barreling not the proof brings the taste and this one came up short.    Oh is was familiar but the heat ran the barrel over like a Peterbilt runs over a squirrel. Could use a heavier toasting of the oak me thinks or perhaps a longer barreling. Who knows. But what I can say is ice or a water back isn't the answer. What kills one kills them both. Sad. It is a pleasant drink....if you have little to compare it to.

      Bridgestone vs Goodyear tires?

      By Grumpy Bear · Posted

      I've had exactly one set of Bridgestone. Lasted five year and 125,000 miles and had I known better 15oK would have been a cake walk. I would have bought a like set had they not tripled in price since the first set. I removed them at said mileage with 5/32" remaining in dead even wear all four. They were fuel efficient, quite, comfortable and predictable.    Early on I got a very good alignment checked at least once a year, sometimes twice; kept the tires properly inflated, balanced and rotated. And I've found that many a tire issue can be avoided with great maintenance practices. Lot's of tire dealers will do rotation and balance (simple) for free for as long as you own the tire they sold you so no excuse not to.    Bead prep, alloy integrity and stem health have a huge impact on inflation stability. There are more mountings done poorly that perfectly. Finding a good tire guy is gold and as important as finding a tire you like.    That 3X price increase now two sets of "other tires' later is starting look like a bargain.      Bad maintenance kills more tires than bad tires.

      Wow I'm in a pickle. (Broke down truck) and a story.

      Atlas, you kill me As aggravating as a project like this can be you have been unable to hide your fascination with learning and using that angst against this beast like a Ninjitsu Master. It amuses you, admit it now.      BTW, love your writing style. 😉
