    i have a 73 k5 with the NP203 and manual hubs. i have recently noticed a strange grinding noise upon decel coming from the left front wheel. it sounds almost like axle splines.....it goes away when i start accelerating again. also , i tdoesn't always occur. i took apart the hub on both sides to see if there was any obvious problem, but nothing. any ideas?

    If the 203 is still full time I would start looking at the front drive shaft CV. If it's full time and your running it in LOC with hub unlocked your not helping the 203. Yes you can do that for a while but it puts extra slop into the driver train and wears on the locking collar.

    yes the 203 is still full time, but i don't run it with out the hubs locked, i know about the wear it causes. u joints are all good, did a recent inspection and replaced a couple. front driveshaft CV is also good.
    is there anything in the hub/bearing area that could cause this?
