Regular Checks
Wheel Nuts
Wheel nuts should be checked on a regular basis usings a torque wrench and tightened to 140 Nm.
It is not recommended to use a rattle gun, as there is no way to know how tight the nuts are.
Overtightening will damage the studs and will cause them to fail prematurely. Under tight wheel
nuts will cause vibration of the wheel and will eventually cause the studs or nuts to fail.
Initially, you will need to check the wheel nuts at 50kms, 100kms, 250 kms and 500kms, and then
regularly after that. during travel on especially bumpy or corrugated roads, the wheel nuts will
need to be checked more often.
Hitch
The bolts securing the hitch to the trailer are a high tensile bolt and should be tightened to 180 Nm.
These bolts should be checked with a torque wrench every 2500 – 5000kms, depending on the
road conditions.
Suspension bolts
The suspension bolts should be visually inspected daily to make sure they have not moved. They
should otherwise be serviced as per the maintenance schedule. These bolts should be tightened to
180 Nm.
