I just replaced the ABS speed sensor on my 1999 Ford Ranger, Pard was under $20 and took all of 15 minutes to do the job. Could have done it in 10 minutes if I had done it before. Don’t know how much a dealer would have charged.
I would think that if they priced their work more competitively they'd bring in more business. They also wanted over $400 to replace my A/C-Heater blower motor. I found the part online for $35.00 then my son and I did it in under an hour.
