First question
Did ubs69 bighorns ever come out with 4.5 diffs?
Second question Which is easier to change a 4.5 front to 4.3 or a 4.3 rear to a 4.5 including a locker swap?
3rd question. can the spider gears from my 4.3 locked diff be used in the 4.5 that was in the bighorn when I bought it?
As you can guess Im not happy but I suppose its my own fault.
When I bought the bighorn I swapped the locker from the old truck without checking
First decent trip every time I took it out of 4wd it was bound up and wouldnt release until I reversed back a few metres. Just checked it at home and turning the front wheel 10 times gives 22.75 turns on the driveshaft and the rear 22.5 which is a ratio of 4.55 and 4.3. Checked the original rear diff and not only does it have 41 tooth crown wheel somthings been munching on the spider gear teeth Big bite marks all over them
Does anyone have a very good open 4.56 rear diff they dont want?
