Rear main leakage
 
My rear main on Goldie startin to drip. I tight'n the pan, but it was tight. What's involved in replacing the rear main:humm:?? Pain in the arse or what, I guess it's about due, I guess...:nope:

its kind of a pain but its not the worst thing youve ever done. i just did mine yesterday. you gotta pull the transmission, and flexplate (or flywheel). and its behind there. the rear main kit from cummins is about 80 bucks or so. i just used the 60 dollar one from napa because i dont have a cummins store around me.

if you know how to pull the transmission then it aint bad at all. i wish i had the money to do the clutch while i was there tho. check the oil pan gasket while your theere too.

Not too bad:pca1: not too bad and a trani service too, I need it.

:td::bat:they suck.....

and you may discover that the little trapezoid shaped bracket (#11) may be cracked and that could be your leak as well.....

it can be done in an after noon if you know how i did mine in 3 1/2 hours and that's with beer brakes.....:tu:

i never have had any problems with rear mains from napa. not to mention if i do have a problem they always give me new gaskets for free.

a new oil pan gasket is recommended too. you can get away with not doing it but i did while i was in there

i would believe on a 4 wheel drive you could do the oil pan without having to lift the motor couldnt you? just get the bolts under the mount and slide it out?

What's the trapiziod shaped bracket (#11)? I couldn't see anything, oh course I don't know what I'm looking fer, but Is it on the drivers, or passengers side? I bet thats what it is...:humm:
