I'm still working the problems from my last post reguarding the cruise, front end alignment and vibrations. I'm getting ther, but need advice on new gear ratios. I went from stock 245/70 17s to 35x12.5 17s. This threw the computer way off in the truck and the dealer has been trying to aviod helping me out. The cruise issue apparantly can't be fixed with out new gears.They set the cruise to work up to 61 MPH. Whay this number I have no idea, I don't think the know - because no one can explain it to me.
Anyway, I was planning on installing 4.10 gears to help with big tires and towing, but now I'm being told that shorter gears may be better? It seems my only options are 4.10 and 4.56 - with aftermarket gears for this truck. Whic one will help me most..I pull a 3k # trailer on ocassion and would like to run at ~70-75 MPH with it.
Thanks
