Re: XJ rear main seal: replace or leave alone?
 
Monte Castleman did pass the time by typing:

> 1. Replace Front differential fluid (contaminated by water) : $75


Drive a bit then pull/unscrew the plug and stick your finger in
there. If it comes out white/foamy then you have water. If it
comes out dry you don't have enough lube.

Draining and refilling diffs is easy to do although you may
have to jack the vehicle up or remove the track bar to get at it.
(Depends on vehicle)

> 2. Replace missing exhaust clamp: $58


Now that's an expensive load of --------.
2-3$ and a few minutes with a wrench.
Some muffler shops will do this for a few bucks more
if they even charge you at all.

This is a sure sign that your mechanic should be avoided
and all other "suggested repairs" should be looked on
with extreme suspicion.

> 3. Replace rear main seal: $550


Check behind the valve cover up top to make sure that's not
what's leaking.

While the average wrencher can replace the seal, you have to
be comfortable with the idea. But 550 sounds high.

Hi Monte,
To give your Stealer the benefit of doubt, when you brought the
differential in to be checked, it could have be hot and the water mixed
in the the oil turning it a milky brown color. If your mechanic changed
it cold, the water would have condensed and separated to the bottom as
water is heavier than oil, where it fell from the opened cover to the
funnel and storage can unseen. Of course, there's no such thing as a
free inspection. If I had a salesman working for me that didn't a job
out of it, I'd fire him.
