The_Kack Posted October 2, 2013 Share Posted October 2, 2013 Ok, so I just got a Comanche, in good condition minus a few little issues here and there. However, the big issue I'm having with it is that, when in 4h or 4l, and taking a right hand turn or when the axles are off-set (i.e. not parallel to the ground) I get what I can only describe as a rotational grinding/bumping sound. Basically, it sounds like the drive shaft is rubbing on something or has something attached to it that is impacting something else. I checked the shafts and there's nothing there, but I have NO idea what it could be. I did replace the trans mount and it didn't change anything.

88whitemanche Posted October 2, 2013 Share Posted October 2, 2013 Double check the transfer case linkage I had something similar that happened to me.... Link to comment Share on other sites More sharing options...
coyote kid Posted October 2, 2013 Share Posted October 2, 2013 Front spider gears going bad ???? Just a guess Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted October 2, 2013 Share Posted October 2, 2013 Make sure your front drive shaft isn't rubbing the exhaust down pipe. That was my issue. Link to comment Share on other sites More sharing options...
ComancheKid45 Posted October 2, 2013 Share Posted October 2, 2013 Are you on dry ground (ie, Pavement) when operating in 4wd? Link to comment Share on other sites More sharing options...
The_Kack Posted October 2, 2013 Author Share Posted October 2, 2013 Thanks for the ideas guys. And no, I know the issue with the T-Case locking on dry pavement. I noticed this two months after I bought the truck because it flooded my road and making it through the slop, I had to use 4H. Had it not flooded it probably would have been winter before I noticed the issue. I'll get around to checking everything tomorrow evening and Thursday.

Blue88Comanche Posted October 3, 2013 Share Posted October 3, 2013 Make sure your front drive shaft isn't rubbing the exhaust down pipe. That was my issue. I have the same issue, and when I swapped the newer non cad D30 I can hear it rubbing on the exhaust when I make sharp right turns Link to comment Share on other sites More sharing options...
The_Kack Posted October 4, 2013 Author Share Posted October 4, 2013 It uh... It is the drive shaft on the exhaust... :doh: My question now is... how do I fix that? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted October 4, 2013 Share Posted October 4, 2013 Do you have a lift? If so, is the front axle absolutely centered? I didn't have a problem like that until after I lifted my XJ and the front axle was pushed over to the passenger side. If so, centering the axle again should help. If that's not your problem, then perhaps a local exhaust shop can bend you a new downpipe that routes a tad differently to fix that? Link to comment Share on other sites More sharing options...
The_Kack Posted October 7, 2013 Author Share Posted October 7, 2013 Thanks for the reply, sorry for the delay in my response. I do not have a lift. I was hoping I wouldn't need a new down pipe as I don't have a cat (emissions free area) and didn't really want to buy one unless absolutely necessary. Do you think it may be possible to ratchet strap it over an inch or so and have it be permanent? Obviously I'd have to go much further than an inch while doing it to get the bend necessary to make it permanent, but I am really hoping this is viable.

The_Kack Posted October 8, 2013 Author Share Posted October 8, 2013 Better yet, would an alignment solve the issue? Maybe? Hopefully? Link to comment Share on other sites More sharing options...
onlyinajeep726 Posted October 8, 2013 Share Posted October 8, 2013 I'm sure it wouldn't hurt, just don't bank on it. I like the way the HO down pipe is routed. One of the few good revisions Chrysler did. Link to comment Share on other sites More sharing options...
The_Kack Posted October 9, 2013 Author Share Posted October 9, 2013 Ok, so, next question is, I read "how" to center an axle, but can someone explain how to "bounce" the axle to get it centered? Thanks for all the help, I'm sorry to be such an idiot about this. I've only had leafed fronts and IFS and they don't seem to be as sensitive as coil fronts.
