So what did they say was wrong witht he Front DS??? did the DS actually break, was it a U-joint, please explain. If just U-joints, then thats easy and cheap.
Depends on which Jeep model you have...
On my 03 Rubi I have a 4" lift and was running the stock front DS, just fine.
You should be able to get stock one from the dealer for about $275 to $325 and after market ones run about the same as well, $300 to $375.
