CV Joints: What Are They?
February 29th, 2016
Many of the vehicles on the road today are front-wheel-drive; for FWD vehicles, the standard way to get torque from the car’s transmission to the front wheels is via CV (constant-velocity) joints.
Many of the vehicles on the road today are front-wheel-drive; for FWD vehicles, the standard way to get torque from the car’s transmission to the front wheels is via CV (constant-velocity) joints. Rear-wheel-drive vehicles use a U-joint at the front and rear of the driveshaft, but a conventional U-joint can’t accommodate as much movement as a can.
These joints are at the end of half-length axles, and transfer torque to the drive wheels while still allowing for steering and the up-and-down motion of the suspension. The inner and outer joints are p ...
Conventional Motor Oil Vs. Synthetic: The Jury Is In
February 25th, 2016
For decades, conventional motor oil was the only way to go for engines. Over the years, conventional motor oils were continually improved, enhanced with detergents, dispersants, friction modifiers and other additives. These additives would improve the oil’s performance and lubricating properties, lengthening the intervals between oil changes and helping to prevent sludge buildup on internal engine parts. In the 70s, multi-grade motor oils were introduced; these oils could perform well at a wide range of operating temperatures. Conventional oil tends to thicken and become more viscous in cold weather and thin out at high temperatures; prior to the days of multi-grade oils, drivers had to use a thinner oil in winter months and a thicker oil in the summer.
The refining process for conventional motor o ...
Don’t Let Auto Repair Problems Ruin Christmas!
December 1st, 2015
The Santas are in the stores, Christmas music is on the radio, and that means that before long, you’re going to be thinking about holiday travel. Winter driving is tough on vehicles for a lot of different reasons, so let’s go over a few things that you’ll want to address before hitting the road:
- Tires: This is where the rubber meets the road…literally. Make sure that you’ve got the right tires for all-season driving and check them for tread depth. The National Highway Transportation Safety Board and state laws require at least 2/32” of tread depth, but you really need at least 4/32” (or 1/8”) to be safe. Here’s an easy and quick way to check. Insert a penny into the tread grooves, Lincoln&r ...
