Tech Tip: Toyota Knock/Pop Noise When Steering Wheel Is Turned
Some owners of select Toyota models may hear a clunk pop or knock-type noise when turning the steering wheel left or right. Use this procedure to lubricate the intermediate shaft and address customer concerns.
New ‘TechTalk By Federated Auto Parts’ Tech Tips Now Airing On ‘Two Guys Garage’
Kevin Byrd and Willie B., the hosts of “Two Guys Garage,” are talking education and training in new “TechTalk by Federated Auto Parts” segments. The tech tips are now airing during new “Two Guys Garage” episodes on Great American Country Network (GAC).
GM Tech Tip: Growl Noise Caused By Axle Nuts
To diagnosis the noise, re-torque the existing front axle shaft nut to 162 ft/lbs and test drive the vehicle. If the noise is eliminated, replace both front axle nuts with the updated part (P/N: 10257766). On vehicles equipped with the police package, add an additional Nord-Lock.
TECH TIP: Mini: Erroneous “Service Due” Message For Brake Pad Thickness
The mathematical calculation made by the Condition Based Services Module (CBS) do not agree with the actual brake wear. The CBS uses inputs like vehicle speed, pedal pressure and rotor temperature to determine if the pads require replacement.
Tech Tip: Generation 1 Wheel Bearings With Integrated ABS Tone Ring
The front wheel bearings listed in this Tech Tip all share a unique design feature. They are all double-row angular contact with a split inner ring. The distinctive feature on these bearings is that one of the two seals on the bearing has a built-in magnetic impulse wheel. Caution should be taken to make sure that the seal with the ABS impulse ring is installed in the correct direction.
TECH TIP: Using a Five-Gas Analyzer to Diagnose Catalytic Converters
One of the most effective ways to resolve emissions issues is by sampling the exhaust gases with a five-gas analyzer. Levels of the five gases can indicate the root cause of the problem.

TECH TIP: Converter Break-In Periods
A replacement catalytic converter needs a proper “break-in” period. If the converter is not warmed-up (broken-in) properly, the substrate inside could be adversely affected and eventually cause the converter to fail down the road.
Tech Tip: Hydro-Boost Tips And Hints
Hydro-boost brake systems are self-bleeding if there is no other problem in the system. Use this initial bleeding procedure whenever replacing or servicing any component in a hydro-boost system. Normal driving conditions will remove air that remains trapped within the system when components are properly installed and there are no flow restrictions in the system. Always refer to the vehicle service manual for specific installation and testing procedures on import and domestic vehicles.
Tech Tip: Low Or Spongy Pedal After Routine Brake Service
Some vehicles may exhibit a low or spongy pedal after wheel end brake service that cannot be remedied by bleeding the brakes. This may be due to a prematurely deteriorated seal in the master cylinder. Remove snap ring and rearmost piston from master cylinder to inspect seals. If any deformation or deterioration of seals is present, replace the master cylinder.
Volkswagen Tech Tip: Solving Suspension Creaking Noise
Select Volkswagen vehicles may exhibit a creaking noise originating in the front suspension while entering steep driveways or over large bumps. The source of this noise could be the forward inner control arm bushing. To confirm if this is the issue, raise the vehicle and remove the wheel on the suspected side.
TECH TIP: WHEEL BEARING HUB AXLE NUT TORQUING
Putting the proper torque on the center nut sets the preload for the bearing and keeps the bearing from separating while in operation. The torque specification for this center nut is critical to the performance and longevity of the hub.
