Idler arm separated from frame

Yesterday I was pulling out from my friends drive way in reverse and then put it in gear and heard a small bump noise, shrugged it off as shifting into Drive before I stopped and drove down the block only to hear it again but more loudly. So I stop and open the hood and peer down into the engine compartment and notice that the idler arm had separated from the frame taking part of the frame with it. Needless to say, I was dumbfounded. I don't need help fixing it, I opted to take it in for some welding, I just want to know what in the heck could have done that. The mechanic said he has never seen that brake like that before. He asked if the truck was modified and I went over the small list. He said that nothing I had done could have done that, not even cranking the t-bars. Any one have any experience with this?

Re: Idler arm separated from frame

Sounds like a factory goof. Was it very rusty? Maybe the factory didn't rust proof the frame there, or a some bad steel. Thin spot maybe? That shouldn't happen to a 7 year old truck.
Glad you caught that moving slow and not at 70mph!

I had that happen once in my car (2x as old as your truck), the frame around the idler rusted away and there was no other rust on the car. I think it was because the exhaust header was very close to it, odd never the less.

Hit? Them tires rub. Rubbin's off roadin.

Mine is half way disconnected. The dealer told me the same. I still need to get mine welded back. Did it cause a problem when it totoly came off. I don't have the money right now and want to wait as long as I can

Re: Idler arm separated from frame

When the arm broke I couldn't turn very well. The loose arm would run into things and stop the wheel from turning. When the arm moved and the wheel could turn it was almost efortless and driving was difficult because every little bump made the wheels turn. I took it in and they welded a peice of metal about 1/2 inch thick and replaced the idler arm. It was $275 parts, labor and towing. To answer you question 88blazer, it wasn't any more rusted then the rest of the fram. In fact as far as I can tell the only rust on the frame is surface rust. I think it was just a flaw in the steel that finally reared its ugly head. This ticks me right the hell off. I was so close to haveing enough money saved up to buy my friends engine and now I have to practically start over again.
