How much would it cost to replace a bad universal joint on a 2003 Jeep Liberty?

Well, if it is a front driveshaft, the issue is a CV joint and you'll have to remove the driveshaft and take it in to be rebuilt. Taht will run you $150 or more. If it is a rear driveshaft, it will be cheaper if you remove the driveshaft and take it to a driveline shop where they can press in a new u-joint.....I'd recommend you replace both. A guess? $60 to $80
