Non Posi to Posi-differential

I have a locking from differential in my 1994 Grand Cherokee. I dropped the front drive shaft to make it rear wheel drive awhile ago, but I have one problem. Besides beating the living piss out of my transfer case, my rear end is not a locking rear. Is there a way, at a minimal cost, to make it locking? Also, I want to make my truck permantly a rear wheel drive. Is it possible, knowing I have to have a custom driveshaft made, to make it that by just removing the transfer case?

The Powertrax No-Slip Traction Systems are the latest design in traction-adding differential technology. They combine the smooth operation of a limited-slip differential with the traction performance of a locking differential. A precise synchronization mechanism eliminates the ratcheting sounds typical of other locking differentials. Special gear and spring designs reduce the backlash, and, therefore, the driveline windup. Only ultra-strength material that is 67 percent stronger than titanium is used. Installation is simple because no ring and pinion setup is required. In addition, no special tools or oils are needed. Step-by-step, model-specific instructions are provided with every kit.

I am not 100% sure on this, your transfer case is most likely bolted directly to your trans. Therefor your trans will not have a tailshaft housing capable of accepting a slip yoke from the driveshaft. I think you would have to change the output shaft and install a tailshaft housing (may be mounting differences) or there may be a 2wd version of your existing trans, and swap them out.

rick458 did a simple copy and paste of information for an axle that your Grand Cherokee was simply NEVER equipped with from the factory.

Quote:
As the Grand Cherokee matured, Chrysler continued to add new features and models. A 2-wheel drive version was added during the '93 model year,. . .
Meaning you CAN find what you need to do this right.

Your rear axle "should" be a Dana model 35c.
Your rear axle "could" be the Dana model 44.
Your rear axle "could" be the optional Chrysler 8 inch axle.
Go here to positively identify your axle.

Your Jeep could contain any of the following engines as an option.
The 2.5 liter 4 cylinder, 4.0 liter 6 cylinder, 5.2 liter or 5.9 liter 8 cylinder.

Your Jeep could also contain any of the following transfer cases.
The New Process- 208, 219, 228/229, 231, or 242.
Simply crawling under and looking on the transfer case for the identification tag will positively answer which one you have.
Or click here to follow the links to identify your transfer case.

Thanks for the help, but I am still wondering if I can do this, now, what one of you was saying was to remove the transfercase and then get a different end to the tranny, what would something like that cost, and also how much modding and/or work is involved in this? Also, what can I still do to make my rear axle locking, I have the Model 44 rear differential, also, it is the same in the front. so how would I go about making the rear a locking?

i wasnt aware that removing the front driveline damaged the txr case but okay. all you need to do is find someone with a Lincoln welder to weld your gears up inside your differential. known as a Lincoln Locker. end of story.

as for your tailpiece you will need on your tranny go to www.advanceadapters.com the prices are there too

If you are driving this anywhere but on the drag strip, do not weld the rear spiders. It will not only be annoying but dangerous.
At "minimal cost" run through the transfer case as you are. If you do not want to run through the t-case, either replace the output shaft and tail housing or get a 2wd trans.
As for cost who knows. Call a trans shop and see what they would charge to do the shaft swap, search for a replacement trans and compare cost. There may need to be fabrication done for the swap.(that is half of the fun)
As M&M said starting in 93 2wd versions were sold, so you should be able to locate the parts to do it.
For your rear axle, I have not searched but with all of the off roaders that have the Dana 44 there has to be something available.

Appreciate all the advice. Now, 1ownerT, how would welding up the rear spiders be annoying and dangerous? Also, to answer bullheimer's confusion. The T-Case can be damaged by removing the shaft due to that the front drive shaft out put will spin with now load, meanwhile all the power, while origionally designed to be split in the gearing of the T-Case between front and rear, is going solely to the rear, causing the rear to wear quicker due to unexpected nuts like me doing this. Now, if the T-Case was to be a 2-HI, 4-HI, 4-HI transfer case(NP/NV242, known as the Selec-Trac) eliminates this problem by allowing you to choose, with the ability to dis-engage the front output.
