parts to replace while transmission is out?


Recommended Posts

Hey all, first time posting here. just got a '91 MJ base from a buddy, everything works well on it except for the clutch. We debated on whether it was the slave or the clutch itself, but the difference is academic: you're dropping the transmission & buying a clutch kit either way.

So I'm in the process of doing that. Not a job I've done before, but this isn't my daily driver, so I've got leisure to go slow. I'll hopefully finish dropping the transmission today.

So, to get to the point: A buddy mentioned that I should replace the rear main seal while I've got the transmission off. After looking at where those are located, what they cost, & the minimal labor involved, boy, I'd have been kicking myself if I didn't go ahead & do that.

So, does anybody have advice on any other parts that fall under that category? Cheap, easy, but hard to get to unless you're dropping the transmission?

What engine and trans do you have?  4.0 has AX15, 2.5 has AX4 or AX5.

 

I don't know about the 2.5.

 

For the 4.0, you cannot get to the RMS from the back of the engine.

 

You have to drop the oil pan to change the RMS.

2.5L, AX 5.  base as base can be: manual everything, short bed, 2WD, etc.  Even if I had to pull the pan, small price to pay for an Arizona truck.  The metal may not have the rust problems others have, but every piece of rubber on this thing is suspect until replaced, our climate doesn't treat it well.  Second job I have in mind for this sucker after I get this job done is to go through every single vacuum hose & replace them all.

 

I get the desire to switch to external slave, but for my desires of just getting it back on the road first & foremost, I'll just go with the current setup.  Sure an external slave is technically better, but at the same time, this slave lasted 90,000 miles, & I'm unlikely to put that many miles on this in 20 years(though I will check that the assembly fits the internals correctly, as I did read the thread about the plastic throwouts replacing the metal ones causing problems because of improper sizing.)
