X98 still has the T90A in it. The T90C is done and ready to be installed. I'm currently running a Lincoln locker in the rear. There are a bunch of improvements planned for X98, but I could not get them all done for this season of wheeling.

Began to collect parts for some winter changes to X98 that didn't get done last year. 11" rear brake backing plates with parking brake provision and hardware. It already has 11" rear brakes but the parking brake is currently on the transfer case. Also parts to make up a stronger tie rod and drag link and "flip" them to the top of the knuckle.

Slow progress. The transfer case parking brake is gone. That provides a bit more ground clearance.




Made up a heavy duty tie rod and drag link. Did a tie rod flip to get it up higher. Also flipped one end of the drag link to level it out.




Made up a new center crossmember to provide more ground clearance. Still need to finish it up. Next up is a skid plate...

Looks good.  How much ground clearance will you achieve with these changes?

... and where did you get your siping tool?

I'm not sure exactly how much better the ground clearance is. Looks like the crossmember will be about 3" better than stock. The transfer case hangs down below the crossmember on the passenger side so the new skid plate will not be flat on the bottom to take advantage of clearance where it can.

I borrowed a the grooving tool from a friend. I really think a utility knife would have worked almost as good since I was siping with a grooving tool.

Finally made some progress on a belly pan/skid plate. The transfer case pan is the lowest point under the Jeep. Originally I wanted to make a multi level skid plate to take advantage of better clearance in other areas. After a couple false starts and wasted time I decided to just go with a simple asymmetrical U-shaped skid. I had it bent up from 3/16" steel plate and then welded on an angled front and rear. It extends up both sides of the frame where it's bolted on. I wanted it to be strong, lightweight, and easy to remove. Turns out it is not so light  ;D 


Here is the driver's side..



I ground down the transfer case drain plug to get a bit more clearance. The flat center section of the skid is just below the lowest point of the transfer case.



Here is what it looks like from below. I don't have the NDTs on it right now to make an accurate measurement but it looks like it will have about 15" of ground clearance.

Forgot to mention that I removed two vertical inches from the exhaust header pipe to get the exhaust system up higher. While working on the new skid plate I noticed that the left rear wheel bearing was bad so it got replaced along with the axle seals. Since I was in there I also removed the "Lincoln" locker and installed a LockRight locker. Didn't want to spend any money on this axle since it isn't what I really want in X98 but there is no telling how long it will take to put together what I do want.

Your efforts to get every bit of ground clearance possible were in the back of my mind yesterday.  I was driving home and found myself behind a Jk...I think.  Could have been a YJ but I can't tell the difference from the rear.

Not the bumper, but the rear cross member or toe hitch couldn't have been more than 6" from the ground.  It looked so odd, I began to wonder if they do a 2 wheel drive Jeep.  Otherwise, it looked like a completely stock Jeep with a cut suspension.  I tried to take a picture while driving, but couldn't pull it off before she turned.

Some Wranglers with smaller factory tires do sit quite low.

Great idea on the skid plate....... I think I'll steal it.  I wonder if it would be a good idea to make a rubber grommet to keep some separation from the TC drain plug and the skid plate.

It has about 3/16" to 1/4" clearance right now. I don't think it will touch from normal powerplant movement. If it does touch it will probably just make an annoying noise/vibration.

Stock rear differential covers are very thin. It is common to damage them while driving off road. Sometime during the summer wheelin' season my rear cover got dented. It was touching the ring gear but it never leaked and no other damage was done. I installed a front D44 cover on the rear last night. The front covers are much stronger than rear covers.

I just meant if the skid plate got dented it could start touching.  I thought about making a rubber washer that was held in place by the drain plug boss.  Thick enough to touch the TC pan and the skid plate.

I had a few questions about my steering so here are some more photos....

It's in winter mode now so the snow plow is installed. The frame is boxed from the round crossmember forward and three tubes are welded in placed for the steering box mounting bolts. The top bolt is above the frame and has that tripod to support it. The box is forward as far as possible and the front bumper is bowed up slightly to fit the box.





Here is the steering column at the firewall. This column was in another Jeep, I would really like to shorten it so it doesn't extend so far out for this application. The stock worm gear was cut off the shaft then the bottom was bored out to 3/4". Then a splined shaft slid into the original shaft and was welded on. I made a plastic bushing to support the shaft in the end of the column. I think Advance Adapters makes a bronze equivalent. All the steering shaft parts are Borgeson steering parts http://www.borgeson.com/





Here is the steering shaft at the grill area. I have a 1" body lift so the steering shaft just fits. You can see the 1" spacer in this photo. The crossmember was dimpled to give enough space for the U-joint. The grill also has a slight bend in the sheetmetal so everything fits.





Here is the tie rod and drag link connected to the right knuckle of the CJ-7 Dana 30 front axle.
