Different gear ratio. Can I drive?

[TN_Soljah808]

I have 4.30 rears and 4.10 front. I was told I can drive but don't engage 4wheel drive. He is a mechanic. Now I'm being told by a nonmechanic that it will mess up. Who is right? I have the 4.30 for the front just no time right now to install.

What's your advice? Safe to drive?

Thanks

Your fine. Just don't engage 4WD. And even if you did, it would only be a concern on hard surfaces like concrete or a granite slab where the tires could'nt slip and let off pressure.

Thanks. I'm so tired from installing the rear. I don't know when I'll want to install the front. Busy weekend with the jet skis.

DO NOT ENGAGE the 4WD period... unless you are on ice and then you will have enough slippage with the two different ratios that it would negate the affects of 4wd, so yeah its drivable in 2wd only

Naw, if he had to on dirt/mud/ice he could use the 4WD. I had to use 4WD several times in my old taco with two different gear ratios just cuz I didn't have time to put the other set in like him and I had no other choice but to get where I was going. Besides, those ratios are very close so the binding effect wouldn't be as great like if he 3.58 & 4.56.

I wasn't telling him its ok. Did I advise him to go wheeling this weekend in that configuration? NO. I simply told him if he absolutely had to use it, he could depending on the surface hes on. I'm not talking out my ass, but from experience.

4.10 front/4.30 rear will just drag the rear if you put it in 4wd. Could be interesting to drive. Better than the inverse...

 

[Mr. Leary]

Your front diff is net even under power when you are not in 4wd, so it doesn't matter. I would not use it unless you are in a low traction environment.

There are people who drive off road with different ratios all the time... I would say its not ideal, but it is done pretty regularly, at least in the rock crawling world.

Been there done that, too. Mine was 3.9x and 4.10 and I didn't have any problems at all and I wheeled it like that for a few months before I got the correct ratio in the rear.

Thanks for the information guys. Not wheeling just want to be able to tow my skis to the lake and not have any problems. What pisses me off is my SS 1.2 kit came in the day after I finished the install of the rear.
