Re: How tough replacing clutch master cyl and u-joints on 86 Cherokee?
 

Thanks for the tips Mike!! I've never used these other products but yep
they'd be worth using I'm sure. Have a preference for PB Blaster or Liquid
Wrench? Have a really great little ACE hardware here that I bet has both.

Also, if you've never tried TriFlow teflon lube it's a great product too. I
use it on my bicycle chains and it doesn't grab as much dirt as WD-40 does
and it's really slippery stuff- you can feel a big difference in pedaling
effort. Having to learn about these specialized lubes and such since I'm now
in salt air/sand blast all the time. Never needed anything except WD-40
before heh.

Hi Skip,
Negative on the body shop...I'm a budding Jeeper..still learning the
trades and still learning the basics. I did take my Jeep into the
local Jeep dealership in Brownsville (Don Johnson) and would not rate
them very highly--they forgot to do a few of the items that I told
them to do. So I had to do it myself. Oh well, learned anyways.

Feel free to shoot an email my way (nickm@rgv.rr.DIESPAMMERScom).
