Seized Idler Bearing, Belt Removed

Hi guys,

I've had a grating/whining coming from the engine bay that I thought was related to my power steering pump. I've basically sealed the hoses running to/from the p/s pump after installing a HICAS lock bar and figured the rear rotor of the pump had finally given up the ghost. After being reassured that driving with it like that wouldn't cause damage, I set about getting all the gear ready for repair - new pump, bypass hose etc.

Anyway, I digress. On the weekend I made a short trip to a local pub for a mate's birthday and when I arrived, there was terrible shrieking and the smell of burning rubber. I figured the pump had seized and was prepared to cut the belt off. When I checked under the bonnet, that belt was fine and it was in fact the air conditioning compressor/idler belt that was red hot. I had the car towed home...

Today I cut off the belt and founf the idler bearing couldn't be turned by hand. I started the car to see if the problem was solved and the noise was gone, but when I revved the engine beyond idle it hesitated first. Why? What else could be going on here?

Cheers,

Nick

      FWIW the depth of the groove in the rubber pad is not super essential, the blocks are rubber and squish a bit. If you are worried an angle grinder will make a deeper groove quick smart

      I mean, if you were to move the jacking points away from the original location, that is, away from the wheels and closer to the centreline of the car, then it will be more likely to overbalance and tip off the supports. Same as we talked about before. I was talking about moving for-aft. If the sill is bent outward or inward, then the car would obviously look unstraight from the outside. Hopefully that hasn't happened either. Again, you can do comparative measurements from the chassis rails to see if there is much deflection.

      Can you elaborate what you mean with your first sentence? I meant move as in the bulge kinda seemed like it got pulled "outward" meaning it got pulled down and to the side with the jacking rail itself, so the load bearing bulge now sits lower than usual and is not level with the sill on the other side of the jack point. Either that or the jacking rail just got pushed in a good bit.

      As well as being risky WRT tipping off anyway. Yeah, I wouldn't expect it to move. Just measure from the rear one to the front one on the good side, then measure that same length on the wrecked side. You will find the notches in the pinchweld, and the jacking pad. Just spray a spot of marker paint or something there.

      but any other area than the bulge you are talking about will just cave in then? The front driver side is pretty bent so I don't know if that will work the way it is now. I can still kinda make out where that bulge is/was but it looks like the position of it also changed due to all the mistreatment? Hard to tell
