    Ball joint

    I have had this truck for 5 years and put about 2,300 miles a year on it. It now has 64,600 ligament miles on a factory stock suspension and I have not been able to get the lower left ball joint to accept grease. I don't know how long it has been like that but the piece of rubber around it feels...

    700R4.output shaft leak

    The slip yoke on my driveshaft has a cap at one end with a hole in the center. The hole on the outside is about a 1/16” and much smaller on the inside of the cap. What is the hole for and could it be the source of an occasional fairly large fluid leak? There is nothing wrong with the output...

    A/C Compressor

    I located a beautiful NOS Harrison model no. 1131622 R4 compressor to replace the fifth automotive store unit. It is set up for R-12 so what needs to be done to prepare it for 143a refrigerant and will the original seals be damaged or adversely affected? Thanks.

    Front bumper opinion on position

    I don't know of any square's close by that I can look at so I'm appealing to you guys/gals. Does this look like the front bumper is positioned correctly?

    Fresh oil

    Is it just me or does anyone else, after laying on the ground flat on your back, think that the engine seems to run a little better and smoother following an oil and filter change?? Just wondering.

    Gas smell

    Hi everybody. I jumped in the stock '84 C10 yesterday to head to the store and started smelling gas about a half block away. I pulled over and raised the hood and saw gasoline pooled on top of the fuel pump. I couldn't see where it was coming from so I headed back to the house and turned the...

    I'm getting up there in years and my recall abilities from the late fifties, when I was working in a filling station, is not so good. Can any of you folks give me any ideas of how to fix a grease fitting that will not accept grease? I have three of them. And BTW, how many grease fittings are...

    Mileage question/opinion

    Hey guys. I recently started wondering if the mileage (52,400 when I took possession on 6/18) was correct or should it have a 1 in front of it. As a fleet truck for the company I was employed with for 27 years, it has had multiple drivers for 21 years before it was parked for lack of interest...

    So, everything has been going well, truck running good so I decided to reinstall the original 195 degree thermostat and put in a new temperature sender to get a more accurate reading. While under the hood, I thought it would be a good idea to check the Q-jet mounting nuts and torque to 11...

    Anti theft devices

    Are any of you folks familiar with steering column lock covers? The best one I have found is a CarGard CG-1AC by Simjack. The problem is they are out of stock and don't know when they will get any more. You can't even find them in used condition. I understand that it's fairly easy and quick for...
