1/30/2024 0 Comments Front end alignment near me![]() If you want a more exact number, enter the three measurements into the calculator below. ![]() If your specs are called out in degrees, take the measured difference between front and rear, multiply by 2, and that will be the approximate degrees. A toe in of about 1/16 to 3/16 should be good. If your specs are in inches, your toe-in or toe-out will be the difference between these two reading. This will be the “Front to Rear” measurement. Now measure the distance from the rear measurement point to the front measurement point. Measure the distance between the pins again, this the front distance. Start the motorhome, have your helper watch the marks you placed on the tire and slowly pull forward until the marks are now on the forward side of the tires at about the 4 (8) o’clock position. Measure the distance between the marks on the backside of tires. With a helper, fish the measuring tape under the motorhome and pull it tight. The actual location of the pin on the tire isn’t critical, place on the tread near the outside to make it easier to measure with the tape. Mark the pin location with a X to make it easier to see and find. This would probably provide the greatest accuracy, just make sure the pin doesn’t puncture a hole in the tire. I’ve hear of people using small straight pins stuck into the tire tread. in the center of the tire, in the center of the tread. On the backside of each tire, at about the 8 o’clock / 4 o’clock position, use a pen, chalk, or something to place a mark on the tread i.e. I used a 4 ft long straight edge method and was able to do this by myself in about 10 minutes. If you’re not good at math, I added an angle “Calculator” near the bottom of this article. If the spec is in degrees, either method will work, but will require a little math to convert the readings into an angle. The tire method will provide direct readings. On older vehicles, the Specification is given in inches and there isn’t any need to convert this to an angle. The tire method will require a helper, the straight edge method can be performed by one person. a fixed point on the tread of the tire, or 2) with a straight edge. There are a couple different ways to make the measurements, both will provide acceptably accurate results: 1) Measured at tires, i.e. Toe angle is the angle of the two front tires in relation to each other, Not the center-line of the vehicle. Although not absolutely required, to get the most accurate measurement, the motorhome should be loaded with its normal stuff and then driven forward onto the measuring spot ( not backwards). The two front tires need to be the same make and model and their pressure needs to be equal. The motorhome needs to be on a reasonably smooth level surface with the wheels pointed straight. With this spec, its possible to have a toe-out, and still be within specifications, but this will impact handling. There are various sources for the F53 front end specifications, but the latest specs seems to be toe-in of 0.06 deg toe in, plus/minus 0.25 degree. Toe angle is typically specified as the angle between the two wheels, not one wheel and the center-line. Always double, triple check your measurements. ![]() You need to use great care when making your measurements to get them as accurate as possible, if you’re measuring on the tire, you’re looking for an measurement error of less than 1/16 of an inch. If you decide to make an adjustment, this will take a little longer, but again, no special tools required. The measurements can be done with a straight edge and a tape measure, taking less than 15 minutes. If you have a truck place do your front end, talk to them about this.Ĭhecking wheel toe angle doesn’t require any special tools or equipment. Over the road (OTR) trucks have the toe-in set at zero or slightly toe-in to keep tire wear to an absolute minimum. I’ve NEVER worn out a set of motor home tires, so I opt for a little more toe-in. More toe-in improves stability, but does effect tire wear. When the adjustment moves past zero and goes to toe-in, this makes high speed more stable and less twitchy. This is really great if driving a race car, but it’s not the desired handling when trying to control a motorhome. If the front end is set with toe-out, this can make the motorhome handling squirrely, touchy and sensitive. Once this adjustment is made, the steering wheel may need to be re-centered. Unlike a car that has an adjustment on each wheel, the F53 chassis has one adjustment that points the front tires in (toe-in), or pushes them out (toe-out). Toe-in adjustment effects tire wear and handling.
