Typical Stealership....... Ordering parts without even looking at it. I had a bad pinion bearing ($90) and they told me a big scary story about my gears were destroyed and LSD was incinerating. I told them to show me; they took me to the service garage and my truck was just sitting there. They dident even look at the rear end, dident even take the diff cover off. I called one of Dodges finest mechanics out, and he said "i can just tell by looking at it".... You get the idea
dealership.
Similar pattern. I took my truck in for oil change, but asked them to check rough idle too. It's bouncing from 600-675 rpm at idle. A little bit of non-manifold ticking, so wanted to make certain not lifter or valve seat related. 54K miles and five months left under warranty. Now's the time.
I believe mechanic listened real quick and then didn't look at anything, just picked the standard sell-up items they normally do: change plugs (mine were just changed at 32K--***** put that I refused plugs in the system too, but I've got a pre-paid maintenance plan that will change them at no add'l cost at 60K so why $ now?), clean throttle body (I have a catch can and have inspected, its spotless), and then the unrelated money maker: your brake lines should be flushed (had brakes done at 40K and did the flush then). Oh, and they recommended a $450 4x4 diff and transfer case fluid change, that I can do myself or get done for half that cost at two or three places nearby. Pre-paid plan doesn't cover 4x4 (my bad for letting wife insist on it).
Never buy this plan!
So, (now equipped with a reliability check on this Stealership) I got my oil changed and shot it with a bottle of injector cleaner when I got home. The good news is they're now using Pennzoil Platinum (above avg. moly), so no tickety, tick, tick!
The injector cleaner has worked through now and the idle has improved too.
So a word to the wise, question everything these guys want you to pay for....
