The Importance of Preventive Maintenance

[Gary Hatt - Publisher BCM]

Preventive maintenance is one of the most valuable investments you can make in your RV. While routine upkeep, such as changing oil or checking tire pressure, is expected, true preventive care takes it a step further. This article explores the broader concept of preventive maintenance, illustrating how inspecting and servicing components before they fail can save thousands of dollars, prevent unexpected breakdowns, and provide peace of mind on the road.

Whether you're managing a fleet or maintaining a single coach, smart maintenance today can prevent costly repairs tomorrow.

Was that caused by unsufficiently-tight rear suspension U-bolts for the leaf springs (assuming it was a leaf-sprung bus)?   I can't tell exactly what suspension this bus had.

I'll soon be replacing my rear axle's U-bolts on one side, so this picture is a sobering reminder for me to tighten the new ones correctly.

Yes, it is a good idea to replace your U-bolts yearly just to be sure.  And don't buy threaded rod and bend it using a Smoke Wrench like my dad did on his Jeep one time.

I have to replace the U-bolts on the right side because they're too short to accommodate some spacers I need to put between the spring and axle (long story).   I'm having the straight blanks forged now, then I'll have them bent at Franklin Truck Parts on their bender, then I'll have them heat treated to restore their hardness.   I still have to buy a torque wrench that will measure over 600 ft/lbs to be sure they're tightened enough.   Lots of work just to level the bus!

The photo is of a air suspension bus you can see the air bag mount on the left side for the air bag.If you look at some air bag suspension you wonder how the rear axle even stays under one

Lots of huge radius rods & bushings!
And they're a pita to replace too.
Just thinking out loud...
