Looking at a 89 9300 need advice

In general, most duel drive trucks have power dividers but not full lockers. I'm only guessing at a percentage, but I'd say north of 95%.

 

Around here that truck is worth 3-5K.

 

I am good with 9300 IHC's, 3406b's, 13 spd's. Truck folks normally go by wheel base not frame length but many do not know how to measure tandems. Always assume the mileage like that is not true. It would have to have been owned by a company that needed a truck for their business not that was trucking for business. An O/O can legally run around 12,500 miles a month and normally has to do that in order to make ends meet. That equals 750,000 miles in 5 years and an 89 is 27 years old. It is not impossible, Ol Blue to the left has not hit 300,000 yet but when it was put on the road the liner o-rings gave out. I also have a 1989 9370 with 400,000 miles showing and 7,000 hours so that might be 1,400,000 miles.
Excuse my rambling, like HD said "salvage value only" unless it has some really good paper work and or you check it out in person.

 

I prefer the heaver hendrickson and camel backs with LL transmissions for those applications but the air rides do better than I thought they would.
The frame is surly equally light 1/4 in. single rail. Some forage boxes have a pretty good frame and can shore up the truck frame if properly installed. Might want some extra support and or x-member at the front of the box. No hard side pulls.
Those trucks get around a lot better if the rear suspension is farther forward than on standard road applications.
Just changed a single axle to a locker with a reman, required housing modification, and about $3500.
Boss went internet trailer shopping. Then gave me two certified checks, two trucks, a driver and a credit card. Two men two days and we returned with to checks. When I made my phone report he said" We already have enough junk to work on come on back". A picture is worth a thousand words and a camera in the right hands can hide a thousand lies.
PM me if your are interested in a 288" M11 4 spring for that kind of money on the east coast.
Sorry for the random scattered thoughts: Just trying to share other peoples expensive education with you and save you some time and money.

 

Two thousand miles is a long way to go and pay top dollar for an old truck with no warranty. Suggest looking for city, county, state, forestry trucks. Some older heavy spec. low mileage, no frills, trucks come along. Some companies, like Trucks and Parts in Indianapolis and Tampa, sell refurbished roll off container trucks with a 30 day limited warranty. One could be bought body off if contracted early in the refurb process but those trucks have worked hard their entire life. Trucks with booms behind the cab seem to frequently have lockers. If you can get a deal on one of those with a sleeper, then sell the boom and remove the sleeper. They have the wheel base and often are low mileage. Falling in love and rushing in frequently has bad results.
