for 1999 f150 fwd....I have a little wobble in the front left tire and and on further inspection i found i do have abs in all four. I assumed that I would change the bearings but my guy at the part store advised me that i have to change the hub...it looks like a big job and my haynes does not have any info on getting me through it....is there any on line info i can review before tackling the job?....thanks for any input
