This required a review! They don't deserve a star. They put the axle together and didn't tell us about a problem they covered up. We took our truck in to have diff. looked at, the axle shafts had already been pulled out along with the studs for the cover. We let them know this and they said they could take care of it. Their version of taking care of it was to put the old stripped studs back in along with stripped nuts, one was missing and they put in a bolt that didn't fit. We called to see what happened and the employee said that they couldn't find the right studs. I let them know that it was a problem that they didn't tell us and we needed to find a solution because they had put my truck and my driver at risk. A comment was made that I didn't know what I was talking about, that I was just a driver. In fact I am a business owner that owns multiple trucks, and it's my business to know my trucks. It was shotty work that they covered up. Their other excuse was that they didn't charge us to put it together so what was the problem. It was already leaking, it would have lost all fluid and distroyed rear end. Good thing we were checking the brakes and found this problem before sending our truck on the road.
