Blue Devil "Rear Main Sealer"

[B-train]

I'd skip it and just do a rear cover and seal kit. It's most likely NOT the seal but the rear cover. I had a leak on my 2008 for 40k miles and thought it was the seal.....ended up being the rear cover. Seal was perfect.

So, is that the going price to do a rear main seal on a 4x4 Tahoe?

4x4 Suburban.

I'd just do the rear main. Not difficult or expensive, just the time factor.

I was quoted $800 6-7 years ago. Maybe because mines 4WD. Mechanic said it easiest to pull the engine to replace the seal. I added some AT 205 and it doesn’t leak as badly.

8-$9h at an indi here in SoCal.

I'm surprised they'd want to pull the motor to do the rear main. It's much easier to drop the transfer case, remove the exhaust y pipe, unbolt the transmission, and roll it back on a transmission jack.

I did mine
took me all week
but I'm old

If I did it for someone I'd charge no less $1k
and it would have to be rust free.

I'm one of those that ends up looking at what I could do "while I'm in there." Do the u joints while the drive lines out. Did the transfer case rebuild, input and output seals. (The kit is under $100 with timken bearings) Lol, it's an addiction with me, so I always just plan on spending extra time. The wife is okay with it... In 22 years, she's never broke down on the side of the road it's actually an old habit. I used to work on vehicles with wings that broke the sound barrier, and I just got used to replacing parts based on how many hours they had been in use. Sort of do that with my vehicles now. I have restrained myself though from using safety wire on all the fasteners
