How to replace trailer bearings

To stop the trailer from moving when you jack it up, what should you do?

• Attach it to the tow vehicle

• Chock the opposite wheel

• Ensure the trailer has electric brakes

Answer explanation

you can't rely on chocking the opposite wheel when jacking up a trailer as you would if jacking up a car, as the trailer is likely to move, pivoting around the chocked wheel.

If you are on the side of the road fixing a failed bearing, and don't have a vehicle stand with you, what safety precautions could you take to reduce the likelihood and consequences of the trailer falling off the jack? Select all correct answers

• Position the spare tyre under the trailer

• move the trailer to flat solid ground before jacking it up

• Fix one bearing at a time, leaving the other tyres on for a mulit axle trailer

• Keep you body out from under the car - i.e. out of the line of fire
