Helpful Expert Reply:

If you think the cause for the noise on your 2015 Jayco Whitehawk 24RBS tandem-axle travel trailer is from the normal travel of the suspension components (leaf springs, equalizers and shackle straps), you might switch over to wet bolts. The squeaking noises from trailer suspension can be reduced by replacing standard shackle bolts with wet bolts.

Wet bolts like # TRFA71063 and # 126B2 have a grease zerk fitting that allows you to maintain a layer of grease between the surfaces of those moving parts. This can go a long way to reducing the typical noises from a trailer suspension.

The zerk fitting makes it simple and easy to apply a grease gun like # 30-800 and its cartridges # L54FR. This handy tool lets you lubricate the key moving parts of your trailer suspension any time it starts to make excessive noise.

If you happen to be using a weight distribution system on the trailer note that these too tend to make some squeaking noises as a normal course of their operation.
