I am currently running 4.10 in front and 4.30 in the rear with the E locker so far no problems I don't think the gear spread between the two is big enough to mess anything up. I talked to to a guy who does gears and he said it shouldn't be any problem and he would be suprised if I noticed any difference. For those of you who know gears tell me what you think am I going to break anything?

 

on the road in 2WD - you'll be fine.

put it in 4-hi, you MIGHT be OK for a little while on loose stuff.

4-lo on the rocks and you'll snap teeth on the ring/pinion.

 

Thanks for the info. Anyone else know anything about this?

 

Its gona bind up your transfer case and its gona be hard to shift in and out of 4wd.

 

Do not use 4x4 on rocks / pavement or you will trash your deferential (s) or transfer case.

 

Start looking for a matching set of 4.30's up front or you WILL break stuff

 

not a good idea. why don't you just trade front diffs with the guy you got the third member from? then you'll be set up completely and it's not that hard to swap.

 

That's what I'm going to do we are setting up a date to swap out front diffs so I will be running 4.30 front and rear and he will be running my old 4.10 front and rear. Thanks for all your help guys!

 

A 4:10 vs a 4:11 speard is OK, but a 4:10 and a 4:30 is way too much. I actually installed a new rear diff in a 86 truck, Ordered it by the axle code which said it was a 4:30 and after installing it, drove it and shifted to 4WD on dry pavement (it was the A340H trans/transfer) and the rear end squatted right down until I shifted it into 2WD. The axle code netted me the wrong ratio, turns out it was a 4:10. I suppose in slick off roading, your going to be OK, otherwise, you will be in trouble. Fis it as soon as you can.

 

Thanks I am not going to do any wheeling until the front diffs are changed out which will be a week from saturday. Can't wait thanks for all your help.

 

I know you can run a 5.38 Dana 44 and a 5.29 Toy together. But .20 apart is too much IMO.

 

you get to use the locker yet ?

 

No not yet my water pump just went out and so I'm having that fixed and the timing belt replaced. And then I'll be working on wiring up the E-locker sometime soon. I'll get some good wheeling pics when the E-locker is all set up.

 

I used the locker last night and I can't explain how nice it is to have a locker finally and a selectable locker at that.

 

Roger that. That's why I did an e-locker swap as well. It was worth the pain of the swap to be able to "glide" over whooptie do's instead of rocking back and forth and flinging large amounts of dirt and tire chunks into the lower atmosphere without going anywhere.

 

WHY WHY WHY

 

If you read all the thread you will know why and I fixed it I have 4.30's front and rear now.
