Bad luck, Bad shop or Bad Timing?

[07FriscoTahoe]

Need some advice for you experts. Here is my situation. I have a 07 Tahoe LTZ with approx. 111k on it, pretty stock expect AirRaid CAI, 22" wheels/tires and a Managflow muffler. My truck is well maintaned and has had ZERO issues (mechanical, electrical etc).

Last month, we had a nasty ice storm in Dallas and my rear end went out (G80 locker). It sounded like a box of rocks was in the rear end. As soon as it happened I stopped driving and had it towed to the closest shop. Apparently the carrier bearings on one side exploded and ruined the ring and pinion and the locker (I took pics). I was told the whole thing needed to be replaced - to the tune of $3500. The shop had it 3 weeks (plus a week while I was on vaca). When I went to pick it up last Thur, about 1 1/2 miles after leaving the shop I got a low oil pressure/stop engine warning! I stopped the engine and called the shop. Apparently this happened to them while on a test drive, but the equip they had hooked up showed it as a sensor problem and not an actual pressure issue and that it was ok to drive. Since they failed to inform me before I left thier shop, they replaced the sensor and cleaned the screen at no charge.

On the way home from the shop the 2nd time, I got a CEL and a trac contorl/stabilitrak light. Took it to O'Reily's and they said it was "running lean - P0171). I took it back to the shop this am and they just called and said the intake manifold gasket and the brakelight switch both need replacing. They said they smoke tested and it was coming from cylinder 1.

My question is, could ALL of this been bad timing, bad luck or could something have happened while my truck sat for a month that would explain all of these issues? To me, I'm skeptical that all of this could have happened at the same time, ie conicidece, without some other explaination or foul play at the shop. As I said, I've never had any issues with it and it was fine/not presenting codes when the rear end went out.

Thoughts/suggestions? I don't really want to spend another $550 getting these two things fixed if they are all some how related...

thanks!

This is crazy that all this happened...... but you are doubting the integrity of the shop?

I would mark it up to coincidence.

I mean the rear end going was not their fault...... but I have to ask...... they replaced the whole axle housing? For 3500 I would have just bought a reman unit from jasper or something

To me is just seems crazy that all of this happened at the same time without some correlation. Obviously the rear end thing is no one's fault. They replaced the ring/pinion and put in a new differential kit, bearing kit, spacers etc.

The only reason I am questioning thier integrity, is that when I picked up my truck, the invoice was $500 higher than my quote, with no explaination of why. The shop couldn't reach the guy who did my estimate, so they were nice about it and took that $500 off my total. But now I have new issues (oil filter, intake manifold gasket and rear brakelight sensor issues totaling another $500 for issues I didn't have when I towed my truck to them.

Sounds like coincidence to me as well. No telling what else may be headed out at 110k. Thats right around when mine decided to shit all over the place. $3500 does sound like a chunk. I had to put a rebuilt used one in mine that I paid $1400 for.

If they got you for 3500 for a rear I would assume they want you to leave happy and not question anything. That's a good customer for life in my book.

Brake light switch is common. A 20 DIY fix.

Intake gasket could have been going for 10k already and just showed its head from sitting cold for almost a month.

Yup. Just chalk it up to the pluses of owning a GM vehicle.
