Has anyone converted their X to an R. I was looking at the parts list for both to see what it would take. Would I need to replace the front and rear axles? I don't have an R to measure and compare the lengths of the shafts.
You will need all 4 axles. I have researched this quite a bit. It will work on the 2 seater only, the 4 seater is missing a couple control arm mounts in the rear.
Also, the steering racks are different. The R had less turning radius built into the rack to avoid CV Joint binding and wheel rubbing. If you use the X rack, it will have a better turning radius but the steering must be perfectly centered and the toe must be zero to avoid CV Joint binding.
Here is the list I have...
Front upper and lower control arms
Front brake hoses
Tie rod pipe (ends are the same)
Rear trailing arms
Rear trailing arm pivots and mounting bolts
Rear upper arms and mounting hardware
Rear radius rods
Rear brake lines from the frame back to the wheels and all the mounting hardware
It's been done but does seem like a pricey conversion. Not cheap but something else to consider is going with an HCR long travel kit. The results might even be better than an R conversion and this works on the X4 as well.
