Cruisemaster Suspension Issues Explained

In this brief article we are going to discuss the different Cruisemaster Suspension problems, what the causes are, and Troubleshooting Tips.

What are the most common  Cruisemaster suspension issues? 

The most common  Cruisemaster suspension issues are:

  • Coil Spring Breakage
  • Control Arm Bushing Failure
  • Tyre Scrubbing
  • Shock Absorber Failure

Cruisemaster Suspension Set-up

Cruisemaster is a manufacturer of premium caravan and camper trailer independent arm suspension systems in Australia. The Cruisemaster offers a variety of Caravans and suspension set-ups to suit different Caravan Manufacturer requirements.

Cruisemaster ATX

The Cruisemaster ATX is an independent trailing arm air bag suspension meant for both On-road as well as Off-Road. This is a setup more tuned for Ride comfort.

Cruisemaster XT

The Cruisemaster ATX is an independent trailing arm air bag suspension meant for both On-road as well as Off-Road. This is a setup more tuned for off-road than on-road.

Cruisemaster CRS2

The CRS2 is a dual purpose trailer that incorporates 2 shock absorbers instead of one. The two shock absorbers effectively double the rate of heat dissipation of the damping energy that is absorbed from road vibrations.

CruisemastGT

The Cruisemaster GT is more suited to On-Road applications. The suspension is light weight of the independent trailing arm type.

Coil Spring Breakage

  • Steel suspension springs come with a finite life and hence break at some point, depending on how hard they are used
  • In a suspension that is Off-road oriented, it is expected to see coil spring breakages more often than not

Control Arm Bushing failure

  • In all of the Cruisemaster models, the Control arms are attached to the chassis via rubber bushings
  • Among all suspension elements, the Rubber bushings are the most prone to failure
  • The bushings provide isolation from vibrations, but the trade-off is that in the process of dissipating all this energy, the bushes crack and start to disintegrate
  • Rubber elements are also affected by weather, mud, water, salt etc. 

Tyre Scrubbing

  • Uneven Tyre wear on the wheels is the common symptom of tyre scrubbing
  • The reason this happens is due to the tires being out of their alignment 
  • The best way to deal with it is to get the alignment done at a place that does alignment for Trucks. Car and Van alignment shops might not be able to do a good job.
  • If an alignment did not solve the issue, then it might be the case that the axles have bent. 
  • In order to check axle bend, you can use a straight edge plank or a sheet-metal channel of roughly 1-2 mtr and place it over the edges of both the tyres on the sidewall.
  • Ideally, there must be no gap between the tires and the plank. If there is a gap, then it means that there is an issue with either of the axles
  • Also check the center distance between the axles on both sides. Use the in-built adjustment to align the axles back to the manufacturer recommendations.

Shock Absorber Failure

  • In off-road situations, the shock absorbers have to work more in order to dissipate the energy coming from road undulations. In this process, the shock absorbers convert this energy to heat energy. 
  • The energy dissipation process slowly induces wear in the shock absorber internal parts like the piston and the rod seal and they tend to gradually wear.
  • Shocks absorbers in Off-road situations tend to wear faster than those used in On-road conditions. The CRS2, however, is an exception, since it has 4 shock absorbers that do the job of 2.
  • After the control arm bushings, the next suspension element that is prone to failure would be the shock absorber
