Matt I need your help. Last weekend when changing my oil I found a leak which appears to be coming from the rear main seal. Can you send me anything you can find in the service manual that I can take a look at prior to tackling the job. I know it's a big job and I'm confident I can do it.
You already replaced the front oil seal right? It's similar to that.... except you have to remove the trans.
Procedure is the same as in the 05WK service manual we have a copy of. If you need to, download it here:

Oil seal replacement is page 9-1376.
Hardest part, IMO, is R&R of the trans if you don't have a jack.
Yeah I replaced the front seal over the winter. Now the rear appears to be bad and the leak got worse since last weekend. I'm aware that the transmission and fly wheel need to come out. I just like reading up on on it prior to getting my hands greasy because every vehicle is a little different. I've pulled many transmissions in the past so I'm not too worried. I have access to a lift and my brother works R&R at a transmission shop if it comes down to me needing him. I just need to locate a trans jack. Maybe I can "barrow" one from his shop.
Dude you're set then.
Honestly i used to hate the front seals more just because of all the little crap that usually has to come out. With a good trans jack, as long as the top trans bolts arent hard to get to, getting to the rear main aint bad.
I hear you. My biggest concern is getting the old seal out and the new one in without the proper tool. I guess I'll worry about that when the time comes. If not thats when I call jay to stop by and get the old one out and new one in..haha
You'll probably be alright.... those tools basically "idiot proof" the job. There's always Macguyver methods... :cool:
Exactly. So much work all for a $14 seal.
Just to be sure I'm on the same page, the rear main seal on the engine is leaking? Do you have an idea as to what may have caused it? Or are these vehicles prone to this happening?
I'm just curious.
Yes. It's the rear main crank seal located behind the fly wheel. Im not sure on the exact cause of the leak. I have 110,000 miles on my engine. I was told the 4.7's are known for this.
oh ok, well that stinks. Most engines, the rear main seal doesn't go unless it's high miles or it has some internal failure.
Take pics when you do it. It'll be good info to have just in case. Best of luck.
Oh I'll be taking lots of pictures. Honestly, these 4.7 liters are garbage. There known for a lot of problems.
