| My CJ-7 has a history of wandering all over the road. The gearbox causes flexing in the area where the power steering gearbox is mounted. Does anyone have a fix for this problem? All other front end parts check out ok. All help appreciated. Please e-mail me. k5qm@sbcglobal.net |

Without knowing any other details, I would suspect that you need a steering box brace. In particular, I like the M.O.R.E. (Mountain Off Road Enterprises) setup. We did a review of it about 8 years ago, and it's stood up to 37" tires, lockers, serious rock-crawling, etc. http://www.4x4review.com/products/suspension/more-boxbrace.asp
There are several other units out there that are well manufacturerd too, but we like MORE's simple design.
P.S. - you'll want to check to make sure that your frame isn't cracked where the box mounts to it. If it is, you'll need to weld a brace onto it.

| Thanks for the link. I ordered the gearbox support and will see how that works. We inspected it for cracks while we had it on the front end rack today and didn't see anything, of course that doesn't prove !00% Will see what the brace does for it. |

I hope that helps!
Couple other questions that might help diagnose the issue:
1) Do you have a lift on the vehicle? If so, what kind and how tall?
2) What size tires do you run?
3) Are you running a front panhard bar?
thanks,
Rick |

| Everything is pretty much stock, no lift, no big tires, only major changes is a 91 4.3 v6 and 350 turbo. I have had problems with the gearbox mounting bolts working loose. The last time i applied Locktite to the bolt threads and this time I'm not sure if the bolts are loose again. I get my mig welder bottle back Thursday and plan on tearing into it then. The support I ordered should be here by then. The off road I do is in my hunting area which is all sand with a lot of rough areas created by a bunch of bulls tearing up the trails. |

I would seriously suspect then, that the frame is cracked where the box mounts to it. It's a VERY common problem with CJ's. There are a few companies that also make repair kits for this (essentially a cut piece of steel that either welds or bolts to the outside and/or inside of the frame rail). If it is cracked, it's best to weld it, then scab-plate it, then put the box-brace in. That'll fix it for up to 37" tires, if you ever decide to go big.

| Rick I appreciate your input. I will come back and post whatever I find and do to fix it. Probably be a couple weeks. I looked it over this afternoon and really didn't find anything except some sway bar busshings that need replacing. They will be here in a few days.

If it is indeed cracked, you want to drill stop the crack first, THEN weld it. If you want to get really technical, grind a notch the the crack area first then weld it (it help weld penetrates better and fuses crack more effectively.) |

Not sure where I learned it because I have know about it for a very long time. I likely did in college or R&D where I worked for many years both of which were after Vietnam era service time working primarily on B52's. I also learned about how to properly feather a "patch" in so that it does no create the potential for a crack at the ends of the "patch" due to uneven stress issues around the same time I learned about cracks. I use to work with stress testing some in R&D where parts to instrumeneted with various stain gage to measure stress on parts on a aircraft in flight. Once we wired up a F4 to test the stress on aircraft from battle damage repairs to runways. The aircraft was not expected to survive so we took comfort in that we would not have to de-mod and restore the aircraft because the work to it was extensive but as luck would have it the aircraft survived 2 years of tests and we had to de-mod the darn thing. F4's are very nasty to do this kind of work on. It was difficult find ways to route in all the wiring needed to record the data from strain gages on a special flight recorder that itself was the size of a couple of suitcases back then. (they were still using tape drives) A-10's were fun too because the titanium tub around pilot limited wiring access to that area. |

| The problem is finally fixed. The frame was in good shape, no cracks. Several bolts had worked loose. I had used Blue loc-tite and it failed. This time I used Red and I think it will do the job. I also added a Mountain Off Road Interprise brace from the gear box to the passenger frame. That is a worthwhile addition to any Jeep. Thanks for all the help and ideas.

When you use loctite you need to use a solvent to clean the threads on bolt and the threads in nut or casting otherwise, blue or red, it will not hold. Due to temperatures involved, red is likely a better choice anyway. |
