Squeeling coming from front end...

Depends on what rearend you have. If it is a 7 1/4 the price goes up by $100 just for the bearings unless someone here has a secret source. If all you want to do is the front then use the Schucks website, find your parts, print the page with the price and part number on it (sometimes it is cheaper than the in store price) and bring it to the store.

I would just start out with the front end, so you will need...

seals x 2

bearings x 2

wheel bearing grease

a lot of paper towels

brake cleaner x 3 cans (1 1/2 per side)

Haynes manual and about one free afternoon if you have never done it before.
