Toyota Tech Tip: Front Brake Rattle Noise

Some Corolla and Matrix owners may experience a front brake rattle type of noise when the car is traveling over bumps. Updated front disc brake cylinder (caliper) mountings and disc brake pad support plates are available to eliminate this condition. Conduct a road test to verify the noise condition. Front brake rattle noise will occur when the front tire runs over a depression in the road.

Measure Rotor Thickness, Runout: Stop Pulsation Comebacks Before They Start

Let’s say a vehicle had .003″ of lateral runout when measured at the outside face of the rotor. If this vehicle is riding on 205/55R16 tires, in one mile, the high-spot with .003″ of runout goes past the caliper approximately 836 times. Over 6,000 miles, that spot on the rotor will go past the pads more than 5 million times. Every time this spot passes the pads, a little bit of the rotor’s material is removed. Over the course of those 5 million revolutions, enough material is removed to create a thickness variation that can be felt by the driver. This is why it is critical to measure thickness and runout in a brake rotor and wheel flange even if new rotors are going to be installed.

Arnott Releases New Air Suspension Compressor For E70 BMW X5 And E71 BMW X6 SUVs

Arnott Inc., a leader in aftermarket automotive air suspension products, announced the release of a new air suspension compressor with integrated air dryer for the 2007-2013 BMW X5 (E70 chassis) with rear air leveling, and the 2009-2013 BMX X6 (E71 chassis) with rear air leveling.

How Ride Height Affects Toe Angle

How can a mysterious case of tire wear occur in a perfectly aligned vehicle? It happens and the answers aren’t always simple. To better explain, let’s go back a few decades when I aligned a 1983 Mitsubishi rear-wheel drive (RWD) pickup, only to have it return a month later with a tire scuffing complaint. My conclusion was that many independent front suspensions often require a “custom alignment” to compensate for variations in ride height caused by uneven loading.

Performing An Alignment On Ford F-150 And Lincoln Mark LT Vehicles

The 2004-’08 Ford F-150 and 2005-’08 Lincoln Mark LT are not difficult vehicles to align, but they are difficult vehicles to properly inspect and adjust to the optimal specifications. The main difference with the 11th generation is in the front control arms. The lower control arm is forged aluminum. Upper ball joints have a reputation for failing sooner than lower ball joints.

EPA To Propose Eliminating Use Of 134a In Vehicles, Consumer Products

According to the agency, a proposed rule will be issued this summer to withdraw approval for 134a for use in new motor vehicles and as an aerosol in consumer products. EPA pointed to the availability of substitutes for 134a in both motor vehicles and consumer products including 1234yf, which was approved under SNAP for use on vehicles.

Brake Service On A Volkswagen Routan

The 2008-2012 Volkswagen Routan is a rebadged variant of the Chrysler mini van platform with revised styling, suspension tuning and brake service procedures. So this van has a bit of a split personality when it comes to servicing the brakes. The customers who drive the Routan and the Chrysler minivan are two different customers judging by the TSBs. The Routan has five different TSBs about addressing customers who complain about brake noise. The Chrysler mini-van has zero.

Diagnosing Nissan Front Brake Caliper Fluid Residue

While servicing 2005-’07 Maxima (A34), 2005-’06 Altima (L31) and
2007 Altima (L32 and H32 Hybrid Electric Vehicles-HEV), if you confirm there is oil residue on the brake caliper and it’s not assembly lubricant, refer to the Service Procedure as part of your normal brake diagnostic procedure.

GM Power Steering Pump Replacement Tips

An analysis of returned power steering (PS) pumps that had been replaced for noise, no power assist, no or low pressure and leaking conditions has indicated a high number of “No Trouble Found” results. When attempting to repair a power steering concern, the steering system analyzer should be used to assist the technician in a successful diagnosis.

Relax – R1234yf Is Not The End Of The World

I attended the Mobile Air Conditioning Society’s 2014 Training Event and Trade Show in New Orleans last month. The main topic of discussion was R1234yf, or “twelve-thirty-four” in A/C lingo. There has been a lot of hype about the changeover to this refrigerant. Don’t panic. The reality is that it is not the “air conditioning apocalypse” some are predicting.
