Suspension Repairs

Your 4WD gets more of a work out than your average family sedan—especially when offroading. Ensure a smooth and comfortable ride by keeping your suspension in top condition. It’s also vital for your rig’s continuing performance when driving on bumpy and uneven surfaces. Your suspension needs to be finely tuned to meet the on and off road challenges you throw at it.

Our 4WD engineers can service and repair all your vehicle’s suspension parts, including worn shock absorbers, leaking oil, bush replacement, coil spring replacement, ball joint, control arms and leaf springs. A fully serviced suspension ensures you have optimised control of the vehicle, as well as prolonging the usage of your tyres and improving your braking system.

Transmission Repairs

Most mechanical problems with your 4WD can be attributed to the transmission. Our certified
technicians will accurately diagnose the fault, and repair where necessary. Routine
maintenance of your 4WD’s transmission allows the vehicle a longer lifetime and enhanced
performance and handling.
