Grease is applied to seals and bearings for one reason only, to reduce friction. Friction produces heat, excess heat through incorrect installation destroys bearings.
Is it true that 40% of all bearings do not live their full engineering life due to bad installation practices?

Hot Joints are a common problem to find in electrical connections on your trailers and inside your caravans. A hot joint is an electrical connection that becomes loose over time or connected by only a few strands in the connector ferrule.
The Lanyard on your breakaway switch is likely to have been installed without being shortened. A simple adjustment could save your life.
If you are heavy on the scales, shift weight from the front of the axle set to a more central location. This action will lower the weight on your tow ball, allowing your vehicle to become lighter and therefore brake more effectively.
Bearing Buddy® is a machine fit as opposed to a compression fit. Machine fit sizes are not as flexible as compression fits. Unless you are aware of precautions that need to be taken, you may lose your bearing buddy® on the first bump in the road.
Towing your caravan is not as simple as you would think. Whilst enlarging your existing receiver bar from 22mm to 32mm might not seem a big deal, it will quickly become obvious a this is not a solution for towing your $80,000 rig.

Caravan and trailer bearings can be a contentious issue especially when they fail. Seeing a wheel off a caravan on my way home on Australia has triggered this article. I would appreciate it if you could share this with your mates as many folks forget to do bearing checks. Failed bearings can also cause a wheel to come off and roll into incoming traffic with really nasty outcomes.
If shackles or dee shackles are not stamped, they are not compatible with your safety chain. Safety chains must be stamped at least every 4 links.
“Well, I incorrectly installed my pintle hook and ring coupling equipment, and within one month my equipment is ruined.”
Vibration fatigue in caravans and boat trailers is one of the leading causes of spring failure, axle failure and failures associated with your running gear. Have you ever seen an axle wobble in the middle as its owner drives down the highway oblivious to what is occurring under his rig?
The customer felt the installation was weak and would not withstand the loads asserted by a 10t gooseneck coupling. We agreed and produced a 120mm x 36mm deep dia axle collar that could be welded into position. This collar provided a broader base for the tow ball to distribute the load from the gooseneck horse float.
The right trailer spring choice helps prevents holiday accidents. I hope this helps you when making your trailer spring choices. Yes, these matters are serious and you will need professional help unless you happen to be an engineer or a tradesperson who understand a little basic engineering.

Using the grease nipple on bearing protectors to insert fresh new grease on top of OLD DIRTY grease is NOT recommended as this will accelerate bearing wear. Check grease for contamination before greasing your Bearing Buddyt™
“I do not think I really need electric brakes on my camper as it is pretty light.” is a comment I get all the time.
Most caravan and campers are upgraded because existing 39mm Round Axles and 40mm Square Axles are underperforming. Talk to our experts on how to tune your suspension for maximum loadings.
The correct method using 5mm cable is to run a cable down EACH chassis rail and connect each magnet independently. This type of connection is called parallel.
