I think I have a blown right rear shock absorber on my 98 grand caravan AWD. It makes a big thump when you hit a bump hard. I took it to Midas and they could not fix it due to it being a special type of absorber supposedly sold only at the dealership for around $440 each!! I have also heard that this is a type of air shock that can be rebuilt or refilled cheaper. Does anybody have any experience with this problem? There also has to be a cheaper place to buy the part then the dealer. Any help would be appreciated.

Thanks,
Jon
