hi all, I've priced some diff centres, I nearly got one for $260, but the ratio was wrong. If I put an lj80 (3.9:1) axle onto a sierra (4.1:1) how much of a difference might that make? ie one 4.1 diff and one 3.9. this is not a performance 4by, mainly just bush bashing, so the slight slip probably won't be noticed.
the local (reputable) wreckers will give me the entire axle for $260, but it's 3.9:1.
Any ideas? next nearest quote for a 4.1:1 diff is $400

Sorry but your gonna need the right ratio. Otherwise you'll find that your drivetrrain will bind up. You'll notice this because it'll be VERY hard to get out of 4lo.

you can run .1 differance, so what you want to do wont work.

Tj , Hang on to ya horses - for a start I pretty shore no lj ratios where ever made in 3.9. 3-9 is a sierra 1.3 ratio and its pumpkin is slightly larger then a lj or 1ltr sierra It also runs a larger flange bolt pattern for the uni . _ljs are 4-55 for the 80 ,and 4.73 for the 50.
1ltr sierra is 4.1 -. Now I think Lj 80 Lj50 and 1ltr sierra can live in the same housing - But the 3.9 won't fit in there anyway. :(
Do you know what diff you have ?
Maybe a better solution.
