I'm not a mechanic by any means, so I thought someone could help. I just got an 05 4wd with some major miles on it. It started to drip on the garage floor from the front of the rear differential. Is it something that can be fixed easily or is it going to cost a ton. Didn't want to get ripped off.

 

sounds like a pinion seal leaking. not a big job but you'll need a torque wrench that reads in inch pounds. have a look thru a chilton/haynes manual for the job procedure.

 

i need help with a leak too, but not as serious as the other problem up there.
my 3rd taillight leaks. not bad enough to really worry bout it, like when it rains it doesnt really leak, but when i wash the truck and water is being directly applied to the roof it runs in and soaks the back seat.
how do i fix this...
