good hubs are at your local parts store for 130 or less. moog, skf, or timken. all have a 3 year warranty.
modulemasters.com repairs the abs thing for like a 100 bucks as well. or junk yard for far less. junk yard parts like these are grabbed up all the time, its not a common fail part. new are like what 600 or more? f that crap, its a old car.
what i was saying is for the cost of the repairs, i could get another regal or grand prix tomorrow and thats what they are worth now, around 2 grand for most of em these days, 97-03 of course. 04 up still get some money.
with your shop costs your looking at putting the cars worth into it, and thats no fun. hubs are rather easy do. even if you need to buy tools, your still ahead of the game price wise.
