Depends on the part of the country you live in, and the service you need done.
typicall rates are about 75 bucks an hour.
dealers charge more.
I think edmunds.com use to have maintance schedules for cars and suggested rates for the work.

reading over the edmunds numbers, they are super low, Like 30 bucks labor to repack the bearings.
I know I paid 80 to have the dealer do this and it would of cost 150 if I had 4wd.
also the trans labor is low too.
I think you could add on 50-100% to all of the suggestion Edmunds has.
Your best bet is to post what you need done and other will chime in.
