Mazda Tech Tip: Whining Noise From Automatic Transaxle

Some customers may complain of a whining noise from the automatic transaxle when driving at 10 mph and above. The noise depends on the vehicle’s speed (the more speed, the more noise). The noise also occurs with all types of driving (acceleration, deceleration and steady speed).

Understanding Today’s Performance Brake Components

The first question to ask yourself and the customer is what does brake performance mean and how does it apply to their vehicle? A driver’s expectations can vary depending on their experience and how much propaganda they have absorbed.

2004-2013 Mazda3 Brake Job

The 2004-2013 Mazda3 is based on the Ford global C1 platform, shared with the European Ford Focus and Volvo S40. Nothing is really groundbreaking about the mechanical brake system, but not paying attention to the details can end in a post-brake-job comeback.

TPMS: 2011 Toyota RAV4

TPMS relearns for the 2011 Toyota RAV4 are fairly straightforward and simple. The RAV4 doesn’t have a reset button underneath the dash or within the glove box, meaning technicians don’t have to worry about getting a TPMS relearn malfunction due to the vehicle’s ECU closed loop.

Brake Lubricants: Keeping Brakes Moving

Brakes are the hottest components on a vehicle and they need lubricants that can stand up to the heat. With inconsistent temperatures, brake lubricant also needs to work at sub-zero as well as scorching temperatures.

Transmission Fluid: Just Because It’s Red Doesn’t Mean It’s The Same

Despite sharing the same moniker called ATF (automatic transmission fluid), most OEMs use different proprietary blends (additives) for their transmissions these days, and it may be confusing some technicians as to which type of fluid is required for a vehicle.

Dealing With Swelled Lug Nuts

On a lot of vehicles made during the past 20 years, the manufacturer used a two-piece lug nut that has a chrome cap over the steel lug nut. On the new car lot, these look good on a nice set of alloy wheels. But, in as little as three years, the lug nuts could swell and make removal difficult.

2010-2013 Ford Transit Connect Alignment Specs

The Ford Transit Connect is, perhaps surprisingly, based on the Ford Focus. The front suspension is the same, but the rear uses an axle tube mounted on two leaf springs. The van has a cult following with taxi cab fleets, contractors and private owners.
