A few months ago I had issues with a cv joint on the driver's side. The first replacement failed within hours after the repair (the half shaft seperated completely from the inner joint) and the second has been in use now since about April. I was trying to troubleshoot a low groaning sound (not the wife haha) and after greasing all the u joints I grabbed hold of the inner cv joint and it jiggles quite a bit. The passenger side hardly moves at all. I don't notice any clicking which is typical of these things failing but I find it very strange for this to be normal. Any thoughts?

 

shouldnt wiggle at all.

 

That's what I figured. See, I think the mechanic was just giving me the runaround because he already paid for a tow and replaced the first faulty unit. Shortly after I had the current cv joint installed I noticed a squeaking noise and some movement in the inner joint and so I brought the truck back in figuring another faulty part. This happened after I had some new tires installed at Crappy Tire and apparently they neglected to snug up some of the lugs and the mechanic told me this was the cause. I was a little embarrassed not to notice this myself so I let it go. Of course, now, months later, it seems to be getting worse and I think the part is crap and he should install a new one free. But should I keep going back and getting the same service or go somewhere else?

 

keep going back. eventually he'll stop being an idiot cause he'll be tired of paying for parts. its not a hard thing to do... you could even do it yourself

 

Wrong. A loose wheel has nothing to do with the cv axle. The cv axle slides into the hub. The hub is bolted directly to the spindle which cannot move, so no matter how much your wheel was wobbling or if it fell off, would not have any effects on your cv shaft. AT ALL.
Your mechanic is feeding you a line of BS.
