Re: bellows replacement please help
If all they are replacing is the bellows, that price is way over the top.
I would say you need to find out if that is all that is being replaced. If, you had water in the bellows and the ujoints, gimbal bearing, input shaft seal and yoke have to be replaced, along with some other things, you could easily get to 950 bucks. It also depends a lot if they are using the good OEM parts or the junk aftermarket stuff available. You also need to find out their hourly rate. Lots of difference between a place doing it for $50 an hour with aftermarket parts, and one doing the job with OEM parts with a labor rate of $100 an hour.
In a nut shell, you need to find out all the parts they plan on replacing, and if OEM or not, then find out how many hours they are estimating. Then you will have some idea if it's a good price or bad.
