Dick writes: I have a 2007 GMC Yukon. I want to know if I can begin using Synthetic Trans Fluid. How can I drain the regular fluid out? I have 68k miles and I want another reliable 100k out of it.

Mike: Dick, if you have been doing your maintenance all along, and continue, 250k reliable miles is a good number. As far as your transmission goes, take it to a shop or AMSOIL Synthetic Lubricants Dealer, have the transmission flushed, and go back with synthetic fluid. Doing this should dramatically extend the life of that transmission. Changing to synthetic fluid is almost always better in the long run. This goes for all of the fluids, including the differential fluid.

Dillon writes: I have a 2006 Toyota Tacoma Extra Cab with 110k miles and what they tell me is a failing universal joint. The rear one is bad, but would this be a good time to replace the other ones, even if they are ok?

Mike: Dillon, a u-joint failure can be costly and strand you in a heartbeat. I recommend replacing them all and not worry about it for another 110k miles. Most of your labor is paid by doing the first one, so when the driveshaft is on the bench, go ahead and replace the others. -MH

Kevin writes: I have a 2004 Chevrolet Truck with 102k miles. I have a pulse in the brake pedal when stopping. I was told it was warped front rotors, but I have replaced the front rotors twice with no change in the problem. I have also put on a new master cylinder without making any difference. It is getting expensive, Help!

Mike: Kevin, a pulse in the break pedal tells me the problem comes from the REAR rotors. Have someone check the runout on the rotor to confirm the diagnosis. I’m sure you will find your problem there.

Here is a tip: With holiday travel happening this week, be sure to travel safely. One of the best ways is to that is to have your vehicle checked before you leave. Don’t let an unexpected failure leave you stranded. Get your regular service department or auto repair shop to check your fluids, tires, belts, hoses, and brakes. That way if you find a problem, it can be repaired by someone you trust, not someone that happens to be working during the holiday weekend. -Mike
