For some time now I have been wondering how to mount 1 ton Toyota wheels to a ½ ton 4×4 front axle. I have seen some 4wd vehicles with the 1 ton rear axle mounted on the back, but never with matching front wheels. While the 4×4 front axles will never have a 1 ton rating it would be nice to have matching wheels front and rear; for appearance and to have a spare tire that matches all positions.

← Good

← Better!

I rented a U-haul one day to take a closer look at the 1 ton front end. Originally it seemed like the front rotors had adapters for the large 6 bolt wheels, but closer inspection revealed the rotors are specially made.

Using AutoCAD I modeled a couple of possible designs for a front wheel adapter. With the hub taking up most of the space inside the lug nut area, it’s almost impossible to use a sleeve like the first design. The second plan was to use a larger hub with the 4×4 lugs inside the sleeve. Of course there are many other unanswered issues such as centering and balancing tolerances, additional weight and stress added to the outside of the axle hubs, and if steel is overkill or would aluminum be strong enough?

It would be nice to take a set of original 1 ton front rotors and have them machined out to fit the ½ ton 4×4 axle hubs, but that seems like a difficult task at best.

It’s still unclear how to best mount the 1 ton wheels to the 4×4 front axle. Surely this has been done somewhere before. If anyone has any ideas or seen this before please leave a comment for this article.

Every once in a while I come across something that just makes me wonder- how can it be? Something that is 20 years old, yet looks like it just rolled off the showroom. I really appreciate the care alot of Toyota owners give their vehicles and it really shows from time to time. Here is a great example of a 1989 Dolphin on a true 1 ton Toyota chassis. It has the fuel injected 3.0L Toyota V6 with the 4 speed automatic overdrive transmission. It has rear air suspension shocks, dual rear wheels, match set of LT Goodyear HD radial tires with 90% plus tread left and two spares on board. Main salon includes dinette convertible to bed with storage beneath, a sofa-bed with storage below, cabinets overhead throughout, fridge, sliding door leads to rear bath, sink, shower and cedar-lined closet, double-bed above cab with reading lights and opening windows and large front for light and breezy interior, 3 overhead opening vents with MaxAir covers to shield from rain, mounted TV antenna with internal controls and retraction. Multiple cabin lights that all work. Oscillating fan,house battery monitor, as well as 3 holding tank levels. Full original carpet flooring is clean decent and presentable for age, mini-blinds or curtains on all windows, rear seat belts, aromatic cedar wardrobe closet, separate shower area, wash basin (lavatory), power 12v vent above bath, 16KBTU propane heat furnace for toasty coach during very cold nights, screen door, outside light.

Glossy paint on cab that looks to be original is truly nice. Stripes in good shape for age and show some minor age. Perfect windshield. Camper sides and back show very nice and straight.
