Ok, the D70 is getting really growly, its time to do something about it. Been doing some thinking and searching, and I have come up with a couple options.
1. Rebuild the D70, new bearings, clutch disks and side gears, and install the good used 3.07 R&P I got a while back. Cost is gonna be upwards of $800+/-, as the parts to rebuild the limited slip aren't cheap if I use OE Spicer parts. New Spicer limited slips are about $650+/-, and spider gears, clutches and cups are in the $520+/- range.
2. D80 swap. I have located several D80's of the drum brake variety, both SRW and C&C varieties in 3.54 ratio for less than $500. Fine and dandy, but now the front axle assembly/front axle ratio needs changed. Haven't been able to locate a D60F with 3.54's for less than $600. I have found a gutted housing for $200, also located new Yukon master overhaul kit for $150, and a good used set 3.54 R&P for less than $100. I'll reuse all the new parts I put on the D61F (knuckles out). Not really feeling warm and fuzzy about running a 3.54 R&P in the current D61 as I'd have to use a ring to carrier spacer.
I found a set of axles from a 92 W250 (3.54's) for about $700-800, just swap both in. Not sure if the rear is a LSD or not.
What are you all's thoughts? I'm leaning towards the D80 swap, mainly for the strength, as I run my pile pretty darn hard and the D80 its one stout sucker. The small pinion of the D70 is the only thing that concerns me.
