Get caught up! Oh look turbines!
I've always loved turbines! These are 10.5" wide rims with 4" back spacing, with nearly dead 33x12.5's. 2" inch coil spacer lift and 1" rear (both in prior to installation), absolutely no body lift, some trimming required, and BAM! Compared to Richard's Jeep. Positvie chamber isn't as bad as this photo looks, but it is bad.
Feeling like this rig might get a flair of RAT, maybe.
I went for a run with Garth and Garret not too long ago and this happened. Luckily Garret had spares lol.
So you add up the damage and positive chamber that looks cartoony and I had my motivation. The spare kick came into the shop. It's eventually getting a SAS and painted purple for the wife, so it made a great build jig.
Did some fitting and mock up. I know there is a lot of extra room above the diff but that's a consideration for the future.
I don't really have any step by step pics of the centered diff, but if there is anybody that wants to know I'll gladly explain and post up more pics of it as it sits now. But the most important note, its all factory parts cut and fitted and welded.
Then I started on figuring out the upper arm placement with the diff in place. Nailing the geometry is my main focus.
Then a test fit.
It all looked great and fit nicely, so on to the next step, WELDING!!! We worked long days just getting system finished but it was worth it. The install of this is simple. The first step is to cut out the factory crossmember at the rear of the A-arms, then remove the arms totally by unbolting the front. You need that front set of mounts for install. Once you pull all the factory front diff junk out, and prep the frame, it's time to install. The cradle and new crossmember get lifted into place with a jack, to roughly align the whole system the cradle mounts in the existing front A-arm mounts. Once jacked up so the crossmember is tight to the frame, clamp the crossmember in place. Now to install your A-arms, and knuckles. Then MEASURE EVERYTHING AND EVERYWHERE you can to make sure it's sitting where it should be. The bushings that hold the front of the cradle are slightly undersized to allow fine tuning (shims are added after). Once centered and aligned, weld in the new crossmember. The crossmember is permanent but the cradle and complete system can be unbolted and removed as one unit. Okay some pics now.
The day it began.

My special tool for diff mounts
I didn't document the whole install because I still have to pull it all back out, paint, weld check, lube, etc etc etc. But BOOM in!
I'll give more specs of the parts I used i.e. springs and shocks with the re-install post. But first a full bump to full droop comparison.
Measures out to 12" of travel. 7" up and 5" down from ride height. The wheel base got a 2" stretch forward also. Still need to finish the steering system, tube fenders and paint. It's nearly done.
There was a bunch of lift added to the front with this install so I changed the rear too. The rear got treated to a 3-link/panhard setup, using stock springs and shocks just relocated to give it lift. The trailing arms went from 18" to 36" in length, relocates the pivot to the end of a factory crossmember and nearly matches the drive shaft length. The upper control arm which had a pivot length of 10" and an off center ball joint on top of the axle was replaced with a 30" top link to promote traction and nearly eliminate axle wrap. My panhard is nearly 41" long and almost perfectly horizontal at ride height. All link measurements are bolt center to bolt center.
I used TMR universal link mounts and brackets, as well as recycling stock stuff and finally using the Artec mounts I bought from Chris. I don't have many photos of this yet because we just finished it, but I have a few from the mock up stage. I'll add more later. The wheelbase got another 1.5" rearward stretch.
At ride height, the rear has 5.5" of gap between tire and fender and the front has 7" It looks great. 18" of clearance under the frame and 21" under the rockers. I'll add way more pics and details as I finish it up.
One last little thing. I had to make a header/manifold for clearance past my upper A-arm. It's made using mainly scrap steel and I have dubbed it the "manly-fold" because it's sort of a header. Sounds like you imagine it would, but it only needs to last til spring.
More to come
