Axles And Springs

Dunbier recommends that the suspension components be inspected at least twice yearly for any evidence of loose ubolts, bolts and

corrosion or breakage of the leaf springs. Painted suspension components should be sprayed regularly with products such as inox type

protectants to increase the life of the axles, springs and hubs. Galvanized suspensions require a simular inspection and spraying with the

same products and will add to the life of the components.

Wheel Bearings

Should be checked and repacked or replaced every 6 months depending on trailer use. For a quick check, jack up the wheel and give it a

wobble from side to side as in Fig 1. If there is slack in the bearing you will need to retighten the axle hex nut, then give the wheel a spin, if

noisy then change the bearings. If you un-assemble the hub and there is evidence of rust this will also render the bearings unfit for use

and require replacement. Part Numbers for bearings and seals shown in Fig 2. If your are not experienced in this area seek assistance

from a qualified retailer to change the bearings.

Wheel Bearing Protectors

Checking bearing protectors for sufficient grease, with your finger as shown in Fig 3. Press on the grease nipple if spongy they have

sufficient grease, if firm then they need to be re-greased. Using a grease gun with high temperature wheel bearing grease fill the bearing

protector until the spring loaded cap moves outward to contact the retaining circlip. DO NOT OVER FILL. After each trip, check the level of

the cap and add grease when necessary. prior to launching..
