Review of Dexter Trailer Leaf Spring Suspension - Suspension Kits - K71-359-00 Video

You're exactly right Scott! In order to install the 12" Dexter Electric Trailer Brakes #23-105-106-09 using the 4-bolt pattern you'll need to use the Mounting Bolts and Hardware #BRKH10AS with the 7/16" bolts.

The standard diameter for trailer leaf spring bolts is 9/16 inch which is why the part #E4139 and all similar options have this hole size. We don't have anything with a smaller diameter but my guess is what you have is actually 9/16 inch.

The Dexter Heavy-Duty Suspension Kit for Tandem-Axle Trailers #K71-359-00 will work on axles up to 8,000lbs.

From what I could find out about the axle you currently have, The Dexter Axle #8327872, should work. That being said, it is highly advisable to double check a few things before biting the bullet. First, this axle utilizes the inner bearing #25580 and…

The Moryde wet bolts #MR52HR use a standard 1/4"-28 thread for the zerk fittings.

It sounds like you may have one of 2 things going on inside your wet bolts. I have seen some instances where some particles/dirt get inside the wet bolt and clog the weep hole the grease is allowed to pass through. You can remove the bolts not taking…
