But it can take it’s toll on your vehicle. That’s when you need a knowledgeable and trusted 4×4 specialist.

Common 4×4 Repairs

Your vehicle is subjected to more than most – and as such will require more frequent repairs and maintenance.


The Suspension of off-road vehicles tends to endure more the most cars – when you are driving on rough, rugged terrain suspension components will wear out more quickly. You will need to pay particular attention to struts, shocks, bearings, tie-rods, and bushings.


Uneven terrain can take its toll on the steering components of 4×4’s. If you frequently drive off road beware that your front axle is particularly susceptible to damage through wear and tear.


Due to dirt and debris getting stuck between brake pads and rotors the brakes of your 4×4 can wear more quickly if you frequently drive off road. This will decrease their effectiveness and ultimately affect your safety.


Off-roading tyres not only require attention to maintain the safety of your vehicle they also play an integral role in the wear and tear of your suspension & steering.
