Default Rear End Leak, Please Help

I have a leak in my rear end that needs to be fixed. I was wondering if anyone could tell me what seal needs to be replaced, and how big of a job it is. Thanks for the help!

you're not showing the pinion seal... (from passenger side) but that looks to be the culprit...

Little bit of work for you there. Involves full disassembly of rear end...

Pinion seal. I personally would take it to a rear end shop. It would be a good time to install a set of gears, freshen all the bearings (which helps 10 bolts live longer IMO), and possibly do a solid pinion spacer for strength.

Yep, about $600.00

Dang, thats more than I thought it would be. I have a friend that works on cars and has a Firehawk as well, that I will see if he can do it. How much would it be for all the parts you recommend, and what all do you recommend doing?
- seals
- bearings
- solid pinion spacer, what does this do?
- gears, for added strength or for better acceleration? I have 3.42's now but could go to 3.73's, 4.10's, 4.30's, or 4.5x's?

Any other recommendations, the car is completely stock and has 62k miles?

Thanks for the help!

6 speed, I wouldn't waste your money on the 10 bolt. I'd go with a nine inch rear. Bob
