Update-
As I was doing some road testing and off-road testing of my lockers I had a couple of "Oh Crap!" moments.....
The first O/C: While off-road locked my power steering pump blew PS fluid all over the engine bay. I checked the cap, hoses (both low and high pressure) and all fittings. I couldn't find a leak. So I thought I may have over filled it. I topped it up and cleaned everything up. A couple of days later I was off-road/locked and it did the same thing!! So the inspection revealed nothing, but I remembered I had replaced the front seal, so that seemed to be where the leak was coming from. Heck, this was the original PS Pump with 228K miles on it, so I went and purchased a new OEM P/S pump from my Toyota Parts Guy and put it on. I did have to remove the bracket, but taking one bolt at a time and taking my time I had it off, cleaned, painted and reinstalled with new hoses in about 2 1/2 hours. It runs great!
The second O/C: I'm doing some road testing and about an hour into the drive I notice the volt meter going down! I later check with a volt meter and its' reading 12.2 v. I have it checked by the auto parts store and they say it's "Low" charging....so I visit my Toyota Parts guy and get a new OEM Alt and Voltage Regulator and put it on at the same time as the P/S pump. It now runs at 14.4v and the volt meter is back in it's original spot.
Needless to say, I'll be eating beans and rice at Moab (beer to wash it all down), but since it appeared both the P/S/P and Alt were original I can only hope I get another 200K out of these!
I'm outfitting the back tonight and will be doing some additional road testing before we headout!
