How often do I need to repack my wheel bearings?

Every 2 years or 10,000 km – whichever comes first. Trailer wheels operate at quite high temperatures, and with the extreme temperatures we experience, grease tends to break down. At Wild Mountain RV we call this an ‘Axle Service’.

How often do trailers need a brake job?

Trailer brakes should last the life of the trailer if maintained and used properly. When your bearings are repacked, the brakes should be inspected and adjusted. Most trailer brakes do not adjust automatically (like cars and trucks) and should be adjusted for optimal braking.

Situations where trailer brakes need to be replaced:

  1. Over aggressive braking – brake controller adjusted too high. The brakes will get too hot and result in magnet damage or cracks / extreme wear in the brake shoes.

  2. Faulty break controllers – the tow vehicle is not sending the proper voltage to the trailer brakes.

  3. Faulty breakaway switch, or trailer towed with the breakaway switch pulled – this can cause the brakes to engage while driving and damage the brake assemblies.

  4. Rusted and seized brake assemblies – can occur on older trailers that either have not been used for many years, or where the brakes have not worked for many years.

Should batteries be removed in the winter?

It is always recommended to remove RV batteries in the winter to prevent draws and or freezing. A fully charged battery will not freeze, but all batteries slowly discharge over time. Batteries should be charged fully before winter, removed, and stored. An unheated garage is fine. Batteries can be stored on concrete – it was true years ago that batteries could not be stored on concrete floors, but with modern batteries, that is no longer the case. If you are not able to remove the batteries from your RV,  make sure they are fully charged and disconnect the negative battery wire. If possible, check the voltage 1 or 2 times during the winter while stored – charge if necessary.

When do I need new trailer tires?

Tire should be inspected by a technician every spring and fall. Customers should do a ‘walk around’ before every trip, to look for low or flat tires, and uneven wear. If there is excessive wear, or abnormalities (bulging), tires should be replaced. The recommended life of a trailer tire is 7 years (either by date of manufacture or date of purchase/installation). The DOT code on the sidewall will indicate the week and year the tire was manufactured. Tires that are past their 7 year date may still appear fine, but the risk of blowout increases every year past the 7 years.
