Differential Service at Thom's Four Wheel Drive

Differential Service at Thom's Four Wheel Drive

Here at AutoNetTV, we have national viewers, like your neighbors in CHICAGO, who write to us with questions or feedback. One common question we're asked is: "What is a differential and what does it do?" You may have been told by your Thom's Four Wheel Drive service advisor that your differential needs serviced, or it's seen it as an option up on the service menu. Differential service at Thom's Four Wheel Drive covers a lot of things, so let's first talk about what a differential does.As you drive through a turn, your outside wheels and inside wheels turn at different speeds. Kind of like the cars going around a race track - the ones driving in the outside lanes have a greater distance to travel than the cars in the inside lanes. The differential is what allows the outside and inside drive wheels to rotate at slightly different speeds so that the tires don't hop or skip while taking corners, or lose traction in dirt or snow on C ... read more

Wipe Out! New Wiper Blades for CHICAGO Drivers

Wipe Out! New Wiper Blades for CHICAGO Drivers

When people in CHICAGO talk about vehicle safety, they think of tires and brakes. But do we think about our windshields?

In other words, we don't get new ones until the old ones become a safety hazard. Instead, we need to make wiper blades part of our preventive maintenance routine.Wiper blades should be changed twice a year, in the spring and in the fall. In Illinois areas that experience harsh winter weather, special blades are available that prev ... read more

When Are Your Tires Worn Out?

When Are Your Tires Worn Out?

  Hey CHICAGO area drivers, are your tires worn out? What is the standard for our Illinois streets? How can you tell on your vehicle?While there may be legal requirements for the CHICAGO area, there are safety concerns that go beyond meeting minimum replacement mandates.Two-thirty-seconds of an inch is the depth of the tire tread wear indicator bars that US law has required to be molded across all tires since August 1, 1968. When tires are worn so that this bar is visible, there's just 2/32 of an inch – 1.6 millimeters – of tread left. It's that level of wear that's been called into question recently.We're referring to the tread depth on a tire, it can't move surface water out of the way and you start to hydroplane.In a safety study, a section of a test track was flooded with a thin layer of water. If you laid a dime on the track, the water would be deep enough to surround the coin, but not enough to cover it.A car and a full-sized pick-up accelerated to ... read more
