My Gov Liquidators paperwork finally cleared so after an 1150 mile, 48 hr, round trip to scenic Herlong, CA, I now have a 1992 M101A2 trailer. It will be another month, if you believe the GL website, before I get the SF97 required to register it in CA, but I digress.

In preparation for ordering a new axle I came up with the following. It is fitted with 16 x 6.5" wheels with 8 on 6.5" bolt circle; wheel back space is 4.5". Tires are 235/85, and they clear the leaf springs by about 3.5". I'm going to use 16x7 steel wheels (Sequoia or Tundra) with the same back space and run the 285/75 Revos now on my truck, which in turn will get new and more aggressive 33s".

Spring seat to spring seat = 43 1/8", and hub face to hub face = 63". I plan to order a 60" hub to hub Dexter axle (5200 lb ?) to move the wider tires in a bit and keep them under the fenders. I'm going for electric brakes with a parking brake actuator arm, and will have new spiral flex cables made.

I'm posting this so that anyone else who might decide to try one of these big-ass trailers will have a point of reference. Big Mac
 
I used a 3" dia. Dexter, and all the spring seats that were original equipment...I just cut them off the old axle carefully. Everything matched up perfect on the new install.

My problen was that the rims I was planning on using were "hub centric" and not "lug centric" so I ended up having to use a Spridertrax to convert. Needless to say it was educational.

Here is a fellow over at Expo that just did a nice job on an axle swap out...it may help.

Took about 3 months from auction closing until they notified me for pickup. Now I'm looking at another month for them to produce an SF 97 so I can get the trailer registered. They won't begin an SF97 until after delivery - then you have to provide GL the VIN/Serial No, and then they produce the SF97 - clearly bass-ackwards and probably technically illegal.
