How often should I grease the bearings?+

Proper lubrication, along with bearing adjustment is essential to the function and reliability of your trailer axle. Bearings should be lubricated every 12 months or 12,000 miles. Oil bath axles should be checked each trip through the site glass.

What is the proper bearing adjustment procedure and recommended grease (9K to 15K)?+

Review the axle service manual for instructions and specifics relating to bearing adjustment and lubrication for your individual trailer.

CAUTION: DO NOT mix different types of grease thickeners. The grease that the axles use has a lithium complex thickener. Mixing the grease with a barium, calcium, clay or polyurea soap based thickener agent will cause adverse effects. This may include causing the two greases to harden, separate, become acidic, or pose other hazards and damage to the bearings.

How often should I adjust my brakes?+

It is recommended that manual adjust brakes should be adjusted:
1) after the first 200 miles of operation when the brake shoes and drums have "seated,"
2) at 3,000 mile intervals and/or
3) as use or performance requires.

Why do I have to adjust my brakes?+

Brakes must be adjusted to compensate for the lining and drum wear that occurs during the use of the braking system. Some brakes require manual adjustment to move the lining closer to the drum. Refer to brake adjustment in the support material that came with your trailer.

Why can’t I lock up my electric brakes?+

On an unloaded trailer, you may be able to lock up your brakes if your electric brake controller is supplying full amperage to the brakes. When loaded to capacity, you may not be able to lock up your brakes as electric brakes are designed to slow the trailer at a controlled rate – and not to lock up the wheels on a fully loaded trailer.

What do I need to know to safely tow my trailer?+

Towing a trailer can be a trial. Seemingly minor details – like adding a couple hundred pounds to the rear - can make profound changes in the rig’s stability. By following a few simple guidelines, you can stay on track, towing with the utmost ease and safety.

Why does my trailer sway?+

Tongue weight adds stability. If there is zero tongue weight, the trailer’s center of gravity (CG), the point around where it pitches, yaws and rolls, is centered between the tire’s contact patches. This will provide no stability – specifically in the yaw, or sway. Adding tongue weight, by moving the cargo in/on the trailer forward, pulls the CG forward of the tire contact patches. The drag of the tires will tend to pull the CG back onto the centerline of the truck and trailer. The more tongue weight, the farther forward the CG goes, and the more stability in sway – right up until you add too much tongue weight for the tow vehicle’s rear suspension to handle. Industry wide, the target recommendation for tongue weight is 10 to 12 percent of total trailer weight.

What size hitch do I need to tow my trailer?+

All hitches are not created equal. The weight that your vehicle can tow is specified by the manufacturer and listed in the owner’s manual. Find two numbers: the gross trailer weight (GTW) and the maximum tongue weight. With those figures you can then pick the appropriate hitch; they are split into five classes based on weight:

CLASS 1: 2000 lbs. GTW/200 lbs. tongue weight
CLASS 2: 3500 lbs. GTW/350 lbs. tongue weight
CLASS 3: 5000 lbs. GTW/500 lbs. tongue weight
CLASS 4: 7500 lbs. GTW/750 lbs. tongue weight
CLASS 5: 10000 lbs. GTW/1000 lbs. tongue weight

Most hitches employ a removable draw bar, which holds the hitch ball. The bars come in 3 sizes: 1.25" for small utility trailers, 2" for medium to heavy loads and the new 2.5" for the heavy duty trucks.

Hitch balls come in 3 main sizes: 1 7/8," 2" and 2 5/16." Generally, the bigger the ball, the more weight it can support.
