Checking axles and driveshafts for play

[Alan]

When you're out in the field and you start to feel a little shimmy or some unexpected movement, it's time to take action. What quick checks or feel tests do you rely on to spot any potential axle or driveshaft problems before they escalate?

Lift one wheel and spin it by hand to check for any binding or rough patches. You can also give the driveshaft a twist, if it feels too loose, the u-joints are likely worn out. You might notice looseness before it gets serious.

When you turn sharply, listen for any clicking sounds.
That’s a sign the CV joints or u-joints might be failing. Also, check for grease around the boots,
if it's splattered, they’re torn, and dirt is getting in. You’ll want to replace those soon.

Put the vehicle in neutral and coast to see if you feel any vibrations that change with speed. If there's a vibration that matches your speed, it could be a balance issue with the driveshaft. Also, test the u-joint caps for any play by wiggling the shaft at each joint, if they move at all, they’re worn and need fixing fast.

Get underneath and visually check everything while someone slowly turns the wheels.
Look for any wobble in the driveshafts or axles.
Anything that’s moving when it shouldn’t be is a clear indicator of a problem.

If you notice vibrations getting worse when under load, that likely points to an axle issue; constant vibrations, regardless of the load, usually come from the driveshaft. After a drive, touch the hubs, if one’s significantly hotter than the other, it suggests developing bearing problems on that side.
