Hi, I just became a memeber.
I would like to know if it is possible to make both front wheels on a 88 Chev 4x4 turn under power?
On more than one occasion especially in snow if I get stuck only one wheel at the front will spin while the other just sit's there and does nothing.
Can I make it so it's like the rear with posi-trac and still make it road friendly?
Nope, there is no locker available for the IFS front end. There may be a new one out, but the front end really isnt' strong enough to take the abuse of a locker, so i wouldn't waste your time. Get a good locker in the rear.
Welcome to the board. Now take the time to fill out your profile. This will let us know what you are driving. If you have a solid front axle you can lock it up. If you have IFS and something over a half ton it maybe possible.
