Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
It sounds like your cv boot either ripped at one area on it and lost all or most of its grease and caused the cv joint to fail in the axle shaft here.I have seen this occur before and had to either have the cv joint replaced in the axle shaft or the complete axle replaced.When the cv joint starts to fail it can cause the noise you have here when turning sharp in one direction or the other as it flexes and is pulled and pushed on when turning.If you continue to drive it this way it may fail eventually causing no engagement to the wheel and may leave you stranded.I dont recommend driving it like this here until this is repaired.
In some cases it is cheaper to just have the entire axles replaced instead of the cv joint.You would want to get estimates to see which is cheaper.
