It is an old Jeep with a lot of miles on it. $17,000 is a bit much for an axle and install. are you sure they did not quote SF all the work to be done to include the re gear?
Swapping axles is a simple task You can buy a full up axle for $2000-$5000. Install is relatively simple. There are enough people on this forum that can lend a hand at a wrenching party.
As long as the frame is not bent the axle replacement should not be that expensive. By it back or look elsewhere is a tough choice. take a minute and weigh the options and go from there. You can buy back you Jeep and it will have a salvage title to it. Then you still have to buy an axle as well.
Base Axle Includes: * Ultimate Rubicon JK Front Axle Housing C to C * HD 1/4" Brackets * Thicker 5/16" Tubes * Axle Housing is gutted, Build to your specs * Axle Requires End User to install Fact

PS hear some stories about BR and know one friend that is getting a run around on a simple axle install seemingly going off the tracks... Go in with a plan if you go that route. Know what you want and understand what they are going to do for the quoted price.
