Good Dealerships in Southern California for Warranty?

I'm currently dealing with grinding noise which I presume is from a faulty needle bearing in the front dif. which is a common issue and people seem to hear this noise early on or 20k miles later. There is a TSB for this and the going noise sound goes away in 4wd like it says in the TSB.

I've had my car at a dealership for a week and half and they come up with some bull everyday about how they have to do this test and that test. Then they go on to blame the noise on my larger tires and my lift with a dif drop. More recently, they've blamed my tires again. I've tried to tell them about the TSB and how it is a common issue but they keep telling me otherwise. During one of their "test" they broke an actuator which took another three days to fix. I feel like I'm living a nightmare. I want to try another dealership to get it fixed but I don't want to experience this headache again. A week and a half of keeping my car and they end up breaking other parts and still not being able to address the primary problem.

Long story short, does anyone have recommendations for a good dealership in the southern CA region where they haven't run into any issues when dealing with warranty?

Thank you!

 

What area of SoCal - LA, Valley, Orange County, San Diego, North County, I.E. ??? SoCal is pretty big...

I take mine to HB Toyota

 

I'm in SD but I'd drive anywhere to take it to the right place within a 150 mile range.

 

What warranty issue have you dealt with?
