w124 ball joint press
 
This ball joint press looks very nice - Im thinking of making one myself with 2 1/2 inch thick steel plates.

with 4 bolts pulling this press sits square and will apply a lot of force.

Go for it and let us know how it worked out! Getting the correct dia sleves is key.

Zulfiqar 02-27-2013 04:13 PM

the plates and threaded rods are the easy bits - 20 for a couple of base plates and about 20 or so for some 4140 threaded rod and nuts (Im thinking acme thread)

Im going to see if a machine shop can mill out a few slivers worth of metal from some pieces of pipe to make the sleeves - looks like I only need to mill a seat into one small piece that will push the joint from the bottom.

If it goes smoothly Its going to be a nice joint press.

I believe you would have to notch the lower spacer ring used for removal. The point at which the ball joint area connects to the lower control arm is not flush to the two contact points on the sides used with original equipment special tool.

I used it too.

ive already ordered a couple of 4x4x1/2" steel base plates with 4 holes. for pieces of pipe Im going to visit a metal dealer yard and see if i can get a few scraps of pipes.

Walkenvol 02-28-2013 11:32 AM

I found the right size pipe in my scrap pipe fittings. take a ball joint to the hardware store to see what fits.

Zulfiqar 02-28-2013 12:57 PM

That is also in my head.

Reason to use this is that Ive seen a lot of postings of the HF tool bending out - 4 strong thread rods would prevent that.

would B7 be a good choice with equally strong nuts?

Walkenvol 02-28-2013 02:06 PM

Surely (4) grade 8 machined threaded bolts wouild apply plenty of force?

I did the job and here are the results - my old joints were rusted in place - even the pinch bolt took some caveman methods to let loose - aerokroil and heat also helped.

the joints were the original factory items with a 1994 date. - the press worked flawlessly and the pipe pieces that I used as drifts were a perfect fit. btw these are 5x5 plates I had a freind at work make for me - the plates I ordered never arrived, the threaded rod is from mcmaster carr.

rusted to hell

press working in action - I also used a 4 lb hammer to shock the thing loose in order to break the rust bond

joint pressed out in 10 minutes of cranking - i cleaned up the rusty hole with some sandpaper and it came out looking new - gotta love MB quality.

the worn out joint - it had about 2mm up and down movement and was as floppy as a dead fish

New ball joint in place - lemforder item bought right here from this forum's shop.

Please always use either genuine MB ball joint or lemforder, the W124 and 201 are not the best design, there is a constant pull on the joint and it can be lethal if it separates. So please do not compromise - btw the Lemforder joint is very low cost in the first place and comes with a zinc plated bolt for corrossion protection.

Im thinking of spraying some body cavity wax on the pinch bolt slit to seal it up and prevent and water entrapment.

You are very brave to do that with the spring in place! Nice job though. I have spoken (via email) with that guy in Germany. Seeing as it worked out I might just go ahead and order one.

Zulfiqar 04-07-2013 12:22 PM

if you notice my jack stand under the arm its not even raised 1 notch and the spring is compressed quite a lot too.

So unless the metal square structure of the jackstand lets go Im pretty good.

This press is definitely lots better than the one screw C shaped one as you can really crank these nuts without fear and hit it HARD with a hammer too.

the cost in ordering was about more than a 100 USD, why not just make it, Im sure you can source a place that has some scrap steel plates and also find a place that can drill out holes for you.

vstech 04-07-2013 10:51 PM

meh. I've got a press...

much easier.
pump pump pump. POP! done.

mine is a cheapo 150.00 12 ton unit... I think they are 169 now. of course, you need a spring compressor also.

Zulfiqar 04-07-2013 11:20 PM

I think I jumbled my post - the 100 dollar sentence was for benedict who was speaking of the german guy selling it on ebay.

For me this press is less than 22 bucks tops including the 3 ft threaded rod and nuts from mcmaster carr and it gives you the chance to replace em in situ. Not everyone has the spring compressor handy.
