As someone said earlier in the thread, this is why I don't use shops of any kind unless absolutely necessary. Car, house, yard, tractors, lawnmowers.....doesn't matter, there's always a story afterwards if i use a shop. If you do have a good shop or parts counter person at your local parts store...treat them with the respect that you would your doctor.
I just replaced the LF wheel bearing in my 95 Corolla. Before driving any distance I wanted to be sure of the axle end nut torque as it is a 2 piece inner race and apparently the torque is very important....too tight and the bearing gets hosed, too loose and the race gets hosed. My Haynes said 159 ft lbs but I also read that Toyota revised the spec. So, I call one dealer service dept. Wicked tight says he. He then yells out to a mechanic who says "235 ft lbs". I decide to stop by another dealer on the way home from work in the XJ just to get a 3rd opinion. The service advisor says they just crank it on with the impact hammer..."Our best mechanics don't use torque wrenches for anything. They're so good they just have the right feel for the torque." I ask to speak to a mechanic. He says he doesn't think there is a torque spec for it. He was a good enough guy to look it up for me. I can see him through the window going on the computer to look it up. 15 minutes later he comes back with the spec....159 ft lbs.
Would you have anything worked on there?
My experience after almost 50 years on this earth is that the wrong person working on your vehicle can destroy it in short order. I coiuld go on and on with the few times I had to use a shop.....Speedy Muffler, AMCO Transmissions, local Plymouth (Dodge) dealer, used car dealer where I test drove the car and the slant 6 ran great but needed an "exhaust donut". We'll put one on says he. Picked the car up and it just never ran as well as when I test drove it. Turns out they must have pulled the intake and exhaust manifolds and snapped studs, gooped it up with RTV and put it back together using the remaining studs.
Good luck with your cause,
