    I recently bought a '90 K5 from a guy who had "Lockrite" lockers installed front and back. I have been noticing a "clicking " sound from the hubs lately and seems to get louder the more I drive it. (Especially when cornering) It sounds Like I have little pebbles or rocks in my hubcaps (of course I don't have hubcaps). Any ideas? I have heard Automatic Hubs make this noise before when the spring goes bad, however these are manual hubs. Can anyone tell me what the problem may be and what I can do to get it fixed? Do the lockers contribute tothis problem? (I've never had lockers before)
    Please help!

    Does it happen only in 4 or all the time? If only in 4, I'd guess the u-joints are going bad in the axle. Also, check the hub, make sure it's fully dis-engaged or fully engaged. Roll the truck a little and check it again.
    Does it happen all the time, or only at certain speeds? could be grinding brake pads, although you'd really feel that when you brake. Maybe loose caliper? Bad wheel bearing?
    Jack the truck up and rotate the wheel by hand. see if you can isolate the exact location of the sound.

    Good luck!

    Pull the trim rings and the inner trim peice around the hub off and take it for a drive. Mine was making a noise I swore was the locking hub and it turned out to be the trim ring. The tire just touches the ring when it flexes when hitting the ground.

    Thr clicking noise is normal for lockrites. It is just the noise the gears make when they overun each other to compensate for the difference in inner and outer wheel speed when cornering.
    FYI .Heres a link to more info on lockrites:<A target="_blank" HREF=http://www.powertrax.com>http://www.powertrax.com</A>

    Lock-rites are pretty noisy. Are the front hubs locked when you hear this noise? If not, then that should rule out the front Lock-rite. But the rear Lock-rite will click quite a bit when cornering. Find out for sure if the sound is coming from the front or the back. It may just be the rear locker making its usual racket.
