81minicruiser Posted November 16, 2017 Share Posted November 16, 2017 Howdy, has anyone swapped a Ford 9 inch single wheel axle into a Toyota Motorhome. The one thing I'm worried about is a rear tire blow-out. I'm bumping up to a 15 inch rim so I can get into an E range tire, I would have went with a 16 inch, but I do not have enough tire clearance..

fred heath Posted November 16, 2017 Share Posted November 16, 2017 You got to weigh the rear of the motor home to make sure your tires can carry the weight. A new rear driveshaft will probably be needed unless you can source an adapter to mate the Toyota driveshaft to the Ford axle. It can be done.

81minicruiser Posted November 17, 2017 Author Share Posted November 17, 2017 I'm able to put 16 inch tires underneath the Toyota now. Going with a 245-75/16 E range 2960lbs per tire,should work great. Shortening and balancing driveshaft with new u-joint. It all seems to be coming together..

Derek up North Posted November 17, 2017 Share Posted November 17, 2017 How close to 6000lb do you expect to get on the rear axle? Have you figured out the cost to change the axle ratio to cope with such a large diameter tire? Quote Link to comment Share on other sites More sharing options...
fred heath Posted November 17, 2017 Share Posted November 17, 2017 That's a 30" diameter tire. I'm sure you checked front to back wheel well clearance. Be sure to measure distance from the bump stop to the top of the wheel well. You don't want to damage your tires first time you bottom out.
