I had a wheeling buddy recommend go ahead and weld the rear end and when it gives up go ahead with a swap. What about welding the front. The jeep will be trailered everywhere so I didn't think welding it would be such a bad idea for now.
Hey WCURover90, I have been checking around the intrawebz, trying to find out about the pros, & cons of the [Lincoln Locker] welded spider gears. 1st. thing, as long as you aren't driving on the street, this would be the cheapest way to lock the diffs. For me , it's the only way, I would lock the the D35 rear. It's not worth putting any $$$ into. If I do this, I will also weld the tubes to the carrier housing. The front diff, poses other possible problems. If you weld the front spiders, then the left axle stub, along with the front driveshaft will rotate, driven by the front wheel. Unlockable hubs, would cure this. Also, The right axle will always turn, unless it has a center disconnect, or an unlockable hub itself. Now what I've read, as far as streeting any of this, If you weld up the D35 rear only, tires wear faster, harder to turn, especially if no track bars, or even worse without sway bar. Both the pro's, & the con's, feel strongly about their opinions, as to whether it's safe or not. Also if it handles worse, or no difference. As far as the front goes, on the street, (center shaft disconnected) you'll feel some left wheel drag, In two wheel drive (rear), because the wheel, diff., & driveshaft, are all turning. This won't be too drastic, but gas mileage may suffer A little. This will only work, in two wheel high, & will chirp the tires on pavement, while turning. One last thing, not sure if your Cherokee will have A front axle disconnect, or not. If it has locking hubs, then it won't. Even if it doesn't have locking hubs, it still may not have A center shaft disconnect, & the front driveshaft, will always turn. I'm still on the fence, about either, for the street. Maybe someone could convince me, to go one way, or the other.
