Rear diff. advice
My axle is bad, seals and bearing as well but my car is stuck at shop. Would it be chaper to get a new rear differential? And if i get a lower gear ratio will the front need to be swapped as well?

Unless you can find a good condition boneyard replacement with the same gears, just doing seals and bearings is probably the less expensive route to go. If the gears in the rear end you have are part of the problem already, then its easiest (cheapest) to at least stay with the same ratio so you don't incur the expense of swapping the front gears as well.

One can also compensate with tires of different diameter! 
For instance, a 4.11 rear would require a 33.55", while a 3.73 rear would require a 30.45" (~31x10.50) actual diameter tire with 235/75R15 tires on a 3.54 front.
