believe you can remove the two rear studs and not have to drop the pan if its not leaking

86 was the 1st year of the one piece rear main seal ,the rope seal was used until 59

Why did they go from the two piece seal to the one piece? Its a major rectal itch replacing it this way.

Did the crankshaft turn at any point in time? I noticed that the alignment of the part was180 degrees (almost) opposite from the start of the video.

I just had my transmission rebuild but notice it leaks a lot of oil. My transmission has a warranty and a shop that did oil change said its coming from main seal. Is it some transmission place can fix?

@SuburbanRanch 2 жыл бұрын

@Clendon Robinson You have to pull the transmission to get to the rear main seal. I would think a tranny shop could do it.

@@clendonrobinson6867stop driving it and get a pressure washer or soap and water and plenty of towels. You’re gonna have to clean your undercarriage surface area up. Find the most northern point of your leak after cleaning and run it to temp. and there you go bub. Hope this helps!

The rear pinion seal the same Cannot figure out the specific yolk & pinion size for the truck I've done gone through 2 new yolk & pinion neither pinion seal would go flush with the rear differential and the flange on the seal is like curved and I'm thinking the 1 I need is flat? I don't know I'm just completely confused I even bought 2 separate books for the truck with still no help.

Rear mains common to leak? Seems like mine is leaking oil. Initially thought it was trans fluid but trans is fine, oil is low. So, I’d imagine that’s the culprit.
