you can see in your pic in post #41 it is the external Splines that stick out and make the OD larger; the splines get crushed during installation.
That is why it is not taking 25 tons to press it in. What happend to installing the Grease Fittings on the new Ball Joints?

The use of that tool is fine with the proviso that the boot is removed. Originally, I thought, based upon other discussions, that the tool imparted the force through the ball, but it clearly does not. Due to the configuration of the spindle, a shop would require special adaptors to reach into the spindle and hydraulically press the joint. A typical shop such as ours could not perform that task without those tools. That clamp seems quite strong for the task..........although the force is still significant.............it's clearly nowhere near 50K lbs. |

Is it a straight line from the top of the spindle to the centerline of the joint? It appears that the joint is recessed slightly and you'd need some type of "C" to get in there????

I may try to install grease nipples in situ in my pristine 85 300D, which has 157k and the lower BJ's are still good.

I considered making a (knock in BJ) punch with a long 2" dia. pipe with a cutout and determined it was not possible to get a straight shot due to the bend in the spindle.

Please post your results if you try my red-neck lower ball joint removal method. I understand some ball joints are tougher to knock out than others depending on how much rust is in there. This one came from a 83 240D with 221K, east coast car which had structural rust, sent to the scrappers but the lower BJ was not that badly rusted in. I did wire brush the seams to get some penetrating oil in there and I am sure that helped. What really worked well was how solidly the knuckle was supported by the earth. I did not swing the hammer all that hard, maybe 30% of max that I am capable of. I took a series of small strikes that produced movement. I recall (about 2 years ago), just propping the knuckle upright in a corner and striking with all my might which produced zero results. The knuckle would just bounce and land on the ground.
I would suggest burying it deeper than in this pic, where the earth was dry. Don't forget a plate (or a rock that won't crack) to spread out the load. I used this method again in the same hole (same depth) the next day after it had rained and while it still worked ok, was shifting off center with each hammer strike.

It does indeed have a cut out and that is what allows it to go on straight.

I got a used steering knuckle with a good ball joint already in it, put fresh grease on it and used a new boot. infinitely easier when they are badly stuck, which the deifinately can be. Last edited by Rocket99; 07-23-2012 at 10:02 PM. Reason: spelling |

That is a pretty extreme measure. I can just imagine the frustration of someone reading several DIYs where the Joint came out easily and having His particular Joint in solidly

It's not much of a redneck method. I think every balljoint replacement I've seen has used a sledgehammer to knock them out.
The proper press makes short work of installing them, and no boot removal necessary. Not particularly practical for a single use, but if you're a shop doing these regularly it makes the job a million times easier. |
