Leaking output seal...again?
 

Hello,
Getting a leak from rear output shaft seal from transfer case. Dealer
repaired about 1.5 years ago for about 109.00 (rear seal).
Is it normal for this to leak again so fast?
Is it easy to do myself, or are there special tools. Have OEM manual but
wanted input for experienced folks who have changed it or found a way to
make it last longer.
Should I replace anything else while there? I did change the transfer fluid
about a year ago and filled to hole. Looks like I better check level again.
Although it sure looks like a rear seal, it seems to leak more when parked
on a slope with the front low and rear high. Still sound like a rear?

Thanks!

When a u-joint goes bad it 'usually' vibrates a lot before folks get it
fixed. This vibration will wear down the output and/or the pinion
bushings/bearings until there is enough play to start the seals leaking.

Just replacing the seal is a temporary fix that normally won't last long
at all. You did good getting over a year out of it.... Your $tealer
suckered you if they didn't change the bushing too... They 'like' the
repeat business.

Re: Leaking output seal...again?
 

These seals are notorious for seepage. However, very easy to replace.
Simply remove the driveshaft, pop the seal out with a seal puller ($6.99
Sears or Pep Boys)
http://shopping.yahoo.com/s:Automoti...=Seal%20Puller
and tap in the new seal with a small hammer (use a piece of wood across the
face of the seal to seat it even all around), re-install drive shaft. I
recommend using fine emery cloth to remove corrossion on the short output
shaft where it contacts the transfer case output seal and apply a "light"
coat of silicone sealant around the outside of the seal where it contacts
the t-case. Sometimes this is where the seal will seep. Difficulty level
scale from 1-5, this is a minus 1@ 45 minutes.

Thanks for the input..
Good news / bad..Looks like it is not the output shaft! But all under oil
filter and pans area....mmmm already changed Oil pressure sender not
there...Off to the powerwasher, nice no leaks!!! Have to wait a while and
see where the darn thing is..Thanks again, will let you know..It is oil not
tranny fluid...transfer case up to level.

PS- How does everyone add to or when changing transfer case the fluid? I
made a mess due to not being able to tilt the bottle up..managed with a
trough made from the head of an empty bottle.

Regards
Tom
