Plymouth minivan

On a 91 Plymouth Voyager with a 3.3 engine the rear main seal is leaking
how hard is it to replace? Does the engine and/or trans have to be taken
out? Thanks Shadetree Mech

 

Yes trans or engine has to come out to install this seal. NOTE if the thrust
bearing is worn out causing excessive end play, installing a new will not
help

It must be a one-piece seal as on my 1998 Dodge Stratus. I had a
transmission shop do the repair, as I wanted to ensure that the
transmission was removed and re-installed correctly. The seal had
caused a significant amount of gauling on the flex plate, so it was
replace too. The tranny shop's cost ended up being lest than what had
been quoted by other shops.

Glenn, can the thrust bearing end play be checked with the engine in
the vehicle, or does it have to come out?

Crankshaft end play can be done with the engine in the vehicle.
1.. Mount a dial indicator to front of engine, locating probe on nose of
crankshaft.
2.. Move crankshaft all the way to the rear of its travel.
3.. Zero the dial indicator.
4.. Move crankshaft all the way to the front and read the dial indicator.
Refer to Crankshaft Specification Chart for end-play specification .Wear
