I have a broken u joint and am wondering how much it usually costs to get replaced.
You likely need CV joint and axle replacement. It’s not cost-effective to just replace the CV joint. If there is no other damage, you may get by with about $250 in parts and labor. If the dealer does it, budget about $400.
This is the kind of thing a good independent mechanic can do very well. Avoid muffler shops for this kind of work.
