    I talked to this guy at a good shop near me and asked him about the balljoints today, and he said it was very rare for all four balljoints to go bad, especially where they don't put salt on the roads. Just for curiosity I asked him how much it would be to get them replaced, and the estimate was $800 for all four. How can I check them to see if they really need repalcing? NTB said i needed new ones, but so far they are the only ones that have looked at them. There is a guy in my neighborhood that just came home from college and he said he'd help me do them, and he's done them before. He has an '83 or '84 3/4 ton Chevy with 4" susp, 3" body lift and 38s, and he can help me if I need them, but I'm starting to wonder if i really do.

    According to Chiltons GM repair manual #8577 Chevy/GMC Pickups and suburban 1980-87; section 8-10. step 15.

    "Check the knuckle turning torque with a spring scale hooked to the tie rod hole in the steering arm. With the knuckle straight ahead, measure the right angle pull to keep the knuckle turning after initial breakaway, in both directions. The pull should be 25lbs. or less."

    I think the spring scale is the same one used to measure fish weight.

    In the top ball joint there is an adjustment sleev ,you take off the boltlook inside and youlle see it it take a four teeth socket (hard to find)My local Graves auto parts is ordering me anew one the othe lost two teeth and a new one is only 11$ the thing is to tighten the sleeve down to set preload on the ball joint.

    On my passenger side I can move the wheel and tire up and down. Do this while looking at the balljoint if the knucle is moving up and down balljoints are bad. My drivers side is fine. My 87 has 153,000 miles on original balljoints. If you are doing one side you really only have to do that side. I'll be doing mine in a couple of weeks. Also with bad balljoints truck will wonder when going down the road. If your truck has alot of miles and you have the parts you might as well do it.

    DMK has the idea, put a jack under the axle and get the tire off the ground grab it top and bottom and attempt to rock, watch the ball joints while doing this. Having a friend helps. If you can see the knuckle move in relation to the knuckle then they are bad. If the tire will move, but the ball joints do not, then it is your wheel bearings. My 74 had the original ball joints until 2 years ago and has been running 35's since 77, so they will last a long time if you have taken care of the truck

    I thought I was wrong once,
    but I was mistaken

    The replacement balljoints are nice. I like being able to lube things GM thought never needed to be lubed (u joints too) On mine the uppers can only be greased by pulling the axle shaft out. If I was doing PM correctly this isnt a big deal since I should be lubing the internal hub bearings too

    90K5, Its not that bad at all. Its just time consuming cause you gotta take all that other crap off to get to them. Go for it. If I can do it anyone can.

    Will work for parts, beer and sex.
