While 4wheelin this weekend a grinding noise began in the front end. It happens when you let of the gas and coast. The closest I can compare it too is when the abs engages, the same high vibration. There is also infrequent vibration at speed when the hubs are locked, goes away when unlocked. Any ideas would be apreciated.

Thanks

 

Spindle bushings are a likely culprit, I think there is a needle bearing replacement for them:

x2 for spindle bushings.

There's a writeup in the tech section about how to make a device to make it easier to lube them.

 

Thanks,

I bought the nut from yota and I am welding up the tool tonight
