diesel swap
Love the sub. I did the 6.2 swap on my 90 and i am pleased with the results. I average 18-19 mpg with a combo of city and hwy driving . The swap is basically straight forward if you have a donor vehicle. The little things will wear you out but overall i am pleased. I have a...
Rear axle
Burbs are cool. I love my 90. Suburbans came with 3 rear axles . The 8.5 10 bolt in the 1/2 tons and 2 different 3/4 tons axles --- the 9.5 semi floater and the 10.5 full floater 14 bolt. I found a 10.5 for mine out of an 88 3/4 ton -- direct bolt in . The only thing you have to do...

My 90 6.2 3.73 and 235/75/15 got 18.9 last time i checked commuting to work (combination of hwy speeds and city stop /go)

suburban
Sorry if I posted on another thread , smart phone and big fingers . Anyway I saw a 96 2wd sub with a FF in a salvage yard . Maybe not as common as the semi but still available. I was looking for a FF for my 90 sub and spotted it but found an 89 with a factory FF.
The only number i found was on the face of the hub (n64b) - warn lock o matic on the dial . Appear to be course spline (maybe 8 large splines ). Built like a sherman - very heavy.
