So I've been working on a Toy conversion for the rear end of the 90 after stocking up parts for over a year (http://www.defendersource.com/forum/...ad.php?t=25530
) So far that is going pretty well and it got a bit of a test this weekend at RC. Keith's kit @ Rovingtracks is a nice bit and once I get a disengagement issue sorted it should be good to go on street/trail for a while.
My issue is the front diff. My original plan was to use an ARB 3rd that we thought had 4.10 gearing but turned out to have 3.54's. So at this point I have a 3.54 diff with an ARB carrier, 4.12 Ashcrofts from Justin @ Lucky8, and the stock open diff that's in the truck now.
Tires are 285 SSR's but eventually I might go skinny 35" SSR's or 315/75 KM2's/MTRs.
Swap the gearing in the ARB diff and then look to add: hosing, air supply, extra wiring and potentially new axles. Pros
: Locked front end and an air supply for airing tires or running air tools. Cons:
Cost - already in at $1,300 and would need to add: gear change fee, hosing and wiring for front diff, ARB compressor and axles - quick guess is another $1000 - $1,200
At this point, Keith's Toy Front conversion at $1,800 would have been a cheaper/stronger move.
Try to sell the ARB diff with 3.54's gears to someone that wants to keep stock gears but add a locked rear and recoup some of the costs. Then get the 4.12 gears swapped into the open front diff and keep things simple with stock shafts and carrier. Pros:
Simple, much cheaper (might be able to keep the overall spend bleed to under a grand) Cons:
The Ashcroft R&P looks to be strong as shit, but I could have issues with the carrier and the axle shafts. I won't have an air supply but I haven't needed one since I started wheeling this truck anyways. And there is the CO2 air option as well.
So what do people think of just running a locker in the rear? Or is the stock Rover stuff too weak that upgrading up front is a necessity. I've been wheeling with the 90 for the past few years I've owned it. Up until this past weekend, it was with the stock axles. I don't do anything radical and go out as much as I can but that only works out to about 3-6x year.
Thanks in advance and would love to hear any and all opinions.
