Blue88Comanche Posted May 25, 2013 Share Posted May 25, 2013 yesterday I was on my way home from the junkyard, and i was coming up to a red light when the truck made an awful clunk, and the truck lurched like it popped out of gear. i was able to drive a short distance to a small parking lot. so i started by shifting the tc into 2wd (it was in full time) i pulled forward and back a short distance and it still was clanking, then i removed the front drive shaft, and again it was still clunking. dad noticed that when i pulled forward at some point the rear shaft sorta stops rotating and the diff case rotates upward only for it to snap back into place... I haven't done any off roading sense i installed the rear Aussie locker. the engine still runs fine (aside from overheating due to a bad pressure bottle) I haven't started looking at it yet, hopefully i can tomorrow. I think it may be: Broken ring or pinion TC case issue (broken gear?) however on the plus side while i waited the 1 1/2 to 2 hours for the tow truck i was able to swap the old plastic dash bezel to a wood grain.

GirsMJ86 Posted May 26, 2013 Share Posted May 26, 2013 :thumbsup: on the wood grain, love those things. I really need to find one to go with my black interior. Here's to hoping for an easy fix. I would lean towards rear end issue, but couldn't say for sure. Link to comment Share on other sites More sharing options...
Keyav8r Posted May 26, 2013 Share Posted May 26, 2013 Picked up a wood grain bezel at P&P for my '88. Gonna put that puppy on, if I ever get the dash back in. Picked up several other little upgrades for the MJ there. Now I've just got to get it all back together and running so I can install everything. Why is it every time you fix one thing you discover two more that need to be fixed? Link to comment Share on other sites More sharing options...
jpdriver1 Posted May 26, 2013 Share Posted May 26, 2013 I'm leaning towards ring & pinion ----- btw is that a thermometer on the clock? inside temp or outside? Link to comment Share on other sites More sharing options...
HOrnbrod Posted May 26, 2013 Share Posted May 26, 2013 It's a boost gauge. Probably using just the vacuum side unless it's just an ornament. :yes: Link to comment Share on other sites More sharing options...

I have another insert from a jeep without a clock that I am going to use instead of that one. This way there is not a hole where the clock part was. The vacuum gauge is nice, and its also cool to have a responsive needle lol Link to comment Share on other sites More sharing options...
jimoshel Posted May 26, 2013 Share Posted May 26, 2013 Back when mechanics were real men and not glorified computer analysts the vacuum gauge was one of their most useful tools for analyzing an ailing engine. They were also a valuable aide for knowledgeable drivers wanting to get the most out of their machine. How come there's no icon of a soap box?

jimoshel Posted May 27, 2013 Share Posted May 27, 2013 There are two different springs on the clutch pedal. A strong one and a weaker one. In the 'Power' position the stronger spring is used, bringing the clutch pedal up faster. In the 'comfort' position the weaker spring is used requiring less foot pressure. Thank you for the icon..

Thank you for the icon.. :laughin: Jim, when you click on the button for the smiley's, it'll pop up the bar on the bottom with them. Off to the right there's a tiny arrow to go to the next page of them. Took me awhile to notice that. Link to comment Share on other sites More sharing options...
mvusse Posted May 27, 2013 Share Posted May 27, 2013 I'm guessing the cross shaft. Link to comment Share on other sites More sharing options...
Blue88Comanche Posted May 27, 2013 Author Share Posted May 27, 2013 I'm guessing the cross shaft. The cross shaft was brand new but I guess it can still break, however I havens done anything that should have broken it, all street driving, and normal driving Link to comment Share on other sites More sharing options...
mvusse Posted May 28, 2013 Share Posted May 28, 2013 But what was holding the cross shaft in place.... Link to comment Share on other sites More sharing options...
