When I picked up my trailer in 2018 the owners manual that I was able to download regarding the Turning Point Pin Box only listed the maintenance requirements of checking all of the fasteners and periodically checking the torque values on all the bolts. Seemed easy enough! However the current edition of the manual now includes a specification to check the bearing and grease once per year. Makes sense, but now that opens up a whole new can of worms on how to do a two or three man job by myself (unless I want to pay someone else to do it).
The only YouTube reference i could find was by another owner who built a cribbing support in the bed of his truck to support the Pin Box after he removed the eight wing bolts. Glad it worked for him but it didn't look like something I wanted do on an annual basis.
Fortunately I came across a low profile transmission jack at Harbor Freight that worked out perfectly. The first picture shows the Jack after I removed the wheels to prevent any movement once the Pin Box was lowered.
I then drilled a hole into the plate of the Jack so that I could run one of the bolts used to store the OEM wedge up through the Jack plate and secure the Pin Box to the jack. The hole could have been a fraction of an inch more forward because it puts the head of the bolt a little close to the brackets under the plate that make it a little restricted in tightening the bolt. Also the depth of the threaded hole in the bottom of the Pin Box is fairly shallow because it takes into account the thickness of the OEM wedge and not the thinner jack plate. So I will either use a spacer or pick up a shorter bolt to use in the future.
Before backing under the Pin Box I loosened the Turning Point mounting bolts; and detached the emergency brake box and clamp securing the 7 pin plug. I was then able to put the Jack stand in place and bolted it to the Pin Box.
once everything was secure the eight wing bolts were easily removed and the Pin Box was lowered.
now the Castle Nut and Bearing are accessible.
Since I took the wheels off of the Jack the Pin Box lifted straight back up into its original position. The other nice feature of the transmission Jack are the adjustment controls to make small adjustments as needed to realign the mounting holes.
