I'd like to improve the steering

[t7389sg]

will I need 1 or 2 of these?

Idler arm mount....one, but there may be other worn steering components.

Have the entire steering system inspected, consider having a quality steering stabilizer installed at the same time.

There are other options besides these examples....

there should be 2 on your motorhome chassis but I don't see how those would be an improvement over the stock units, externaly they look identical except for the fancy paint and NO zerk fittings on the Super Steer units, have the entire front suspension/steering inspected for worn componets by a trusted chassis shop.

I have read how these items can improve the steering on a P-32 chassis. I find that my 1991 350LE steers well but not like a modern car. I find it no problem to drive but my wife wants me to teach her to drive this MOHO so I figured I could make it seem more modern to drive. This MOHO can wander a very tiny bit. It is not like you just hold the wheel still and it will track straight. You do have a very small dead space in the middle. I have inspected the steering linkage and it looks great and it passed state inspection so I feel good about driving it but since the super steer units cost over $300 each and I have 2, I may wait to upgrade. These units do not have zerk fittings because they have needle bearings and are sealed. The OEM ones are merely bushings and need grease to last.

I believe the unit pictured above has roller bearings instead of greased bushings in the stock piece. The stock ones are prone to rapid wear. I have heard that the aftermarket is much tighter. Checking the rest of the front end components and a steering stabilizer are good ideas too.

When I figured out the air ride levelers and added an inch to the height of the air bags, it steered better, the frontend stopped wearing out every year, tires lasted longer, ride was smoother, and I wasn't bottoming out on dips. Check your book. It gives the measurement for the air bags. I had to do some cold forming on the lever adjusters. I think I ended up just above the minimum height to keep 2000 pounds on the tag. I've had the tag axle rebuilt and need to check the tag weight again. If I ever get the transmission to work again.
