The bearings seem to be out on my frigidaire dryer (grabbing small clothes between drum and frame) and the tub bearings are also likely out on the washer (sounds like a jet is landing in my house on the spin cycle). Will it be cheaper to repair or replace these?

It depends who does the work. If you do it, it will be cheaper for the repair. If you call a service tech, it can cost you from 130.00 to 300.00. Most likely, a likely price would be about 130.00 each. Be careful though, you can also be taken advantage upon so be careful who you call. Sears is way too expensive.
