Rear main seal leak

[savannahjeep]

I need to replace the rear main seal on my 4.0 liter in-line 6. The repair book states to remove the transmittion. I have read a couple of other entries and they state I will not have to remove the transmittion just remove the oil pan. Is this true? can someone help me?Please explain. Thanks

remove oil pan. loosen cap on the end. emphasise on loosen. rotate seal out with new seal. That is the quick and dirty of it. but you can do it without removign the tranny. The actual job is a little more indepth than this but that is the jist of it.

Be sure that you insert the new seal in the correct direction. If you put it in backwards you will be pumping oil out faster than you can put it in. Also, be sure that you are careful with the new seal as any small nick or cut in it will leak VERY badly as well. You will need to purchase an oil pan gasket too.

get an oil pan gasket for a 95 4.0 cherokee, that way its a one piece and very easy to deal with compared to the older ones (same thing just multiple pieces.)

 

its MUCH easier on a lift

and look up the torque specs on the bearing cap. its stages i think 40-70-80 ft/lb stages.

 

you may have to take the starter out to get to some of the oil pan bolts. and use a brass punch or something to knock the seal out and then grab the part that sticks down with some pliers.

 

here's a good write-up.

i suggest a MOPAR part... i used an offbrand and ended up doing it again. it worked the second time.

 

i think the mopar seal was like 3 dollars more or something. DEFINITELY worth it. go factory with all important stuff

Wildman, nice link. Like the saying goes, a picture says a 1000 words. :cheers:

I read on another post a little while back that they no longer had the double lipped ones. Could have been wrong info. I don't know for sure.

[Wildman]

The only ones I've seen listed are the Double lipped seals. Places like rockauto, and advance only list a double lip rear main seal.

 

You might have read that the single lip seal in no longer available :dunno:
