Greetings,

Another longtime listener, firsttime caller … I have a two-parter.

First: My 2007 Nissan Frontier will soon be due for a rear brake job. I’ve never worked on rear disks. Should I replace the emergency-brake shoes as well as the service brake pads, or will a simple inspection of them do for now? Also, I’ve had varying advice here: should I have the rotors turned, replaced or simply let them be if no pitting or warping is detected?

Second: Last year, my father and I replaced the U-joints on the prop shaft and since that day there’s a vibration around 55-60 mph. Whether I’m in 4th, 5th or 6th gear is irrelevant and the vibration goes away above and below that range. I do remember when trying to remove the old U-joints, my father took a small chunk, maybe a half-inch square area, out of the shaft right at one of the ends, and I’m pretty sure this is causing it, but is there anything I can do about it?

Good Afternoon. This will be my third query to this column, the first being an ill advised plan to put my wife in an old Mercedes hatched in an Afghan Bunker, the Second being for our Afghan Trailblazer that wouldn’t run. The Benz never materialized (thankfully) and the Trailblazer was made to run reasonably well with a fuel filter and removal of the clogged catalytic converter (The EPA man wasn’t coming to Bagram). Sadly about a week after we got the Trailblazer running they collected it in an effort to go to an all diesel fleet. It was replaced with a TaTa pickup.

This actually pertains to a vehicle in my own fleet, my wife appliance grade 2007 Hyundai Tucson.
