How do you determine the placement of an axle on a trailer?
To know how far back the axle needs to be moved, we want to subtract the trailer’s tongue weight from 10 percent of the total weight. Then we will divide this number by the total weight. Then we will multiply this by the distance from the tongue to the axle.
How much toe in should a trailer axle have?
He said there are all kinds of specifications differences out there, so the Technology & Maintenance Council (TMC) has produced a manual of recommended practices on alignment, with a target value of 1/16″ toe-in. “Most tire wear is caused by incorrect toe settings,” Martin said.
How do you calculate an axle placement?
Start by measuring the length of the trailer cargo box or platform, but do not include the trailer tongue. Multiply this length by . 4. The resulting number is the distance from the rear of the cargo box to the center of the axle.
Where should a axle be placed on a single axle trailer?
As a start, you will want to determine the approximate 60/40 location of your axle. For example, if your trailer is 84 inches long, you will want to start with your axle approximately 50-13/32 inches from the front of your trailer.
Should trailer axle be straight?
Should Trailer Axle Be Bowed Down in Middle A trailer axle should actually be bowed upwards in the middle and not downwards. When the trailer is loaded with your boat, that upward bow will flatten out and your tires will make even contact with the ground.
Are trailer axles supposed to be straight?
No, axles should not be bent. To double-check you would need a known straight-edge, like a level or a “square” (which is actually shaped like an L), and hold that up against the axle(s) If you see light between the two then the axles are not 100% straight.
How do you check an axle alignment?
You can check axle alignment by measuring from the center of the coupler back diagonally to the center of one of the wheels. Then take the same measurement to the other wheel center. They should be identical or within 1/8 of an inch, give or take 1/16 of an inch.
