The axle is wider, the braking system is designed for the dual wheels, and the suspension is calibrated for the added weight. Trying to retrofit a single front wheel will likely result in:
* Axle failure: The axle isn't designed to handle the stress of a single wheel carrying the entire weight.
* Steering problems: The altered weight distribution will significantly impact handling and steering.
* Brake imbalance: The braking system is designed for two wheels. A single wheel will create severe braking imbalance and potential for loss of control.
* Wheel bearing failure: The bearings aren't made for the added stress.
* Illegal and unsafe vehicle: This modification would make your vehicle illegal to operate.
To achieve a single front wheel setup, you would need a complete front-end axle replacement, a massive undertaking requiring professional expertise and significant cost. This is not a DIY project. You'd need a new axle assembly designed for single wheels, new suspension components, new brakes, and potentially modifications to the frame. The cost would likely outweigh the value of the motorhome.
Instead of trying to eliminate the bud wheels, consider:
* Replacing the existing tires: If you just want to change the tires, you can replace the bud wheels with new tires of the correct size and rating.
* Addressing a specific problem: If you have a problem with the bud wheels, diagnose the root cause. It's much more likely that a repair or replacement of a single wheel/tire/brake component is needed rather than a complete axle swap.
In summary, avoid any attempt to directly remove the bud wheels. It is extremely dangerous and impractical. Consult a qualified mechanic specializing in motorhome repair before attempting any modifications to your vehicle's suspension or braking system.
