Question Where to buy Monoball ?

I have been looking around and searching, I only see old post.

Dinan doesn't show e39 m5 monoball on their website.
Do they still make them? Can we still buy them, maybe old stock ?

If somebody knows about a group buy for monoball (Dinan or custom made), I would be interested.

Syncro Design Works in the Altanta area makes a pretty slick setup, assuming you're talking about spherical thrust arm bearings. PM me if you'd like contact info

Thanks for the 2 options. Indeed I was talking about spherical thrust arm bearings

Jcbe34 : I didn't post enough on this forum to be able to PM. Can you email me the Syncro Design Works info at [my forum name] at hotmail.com ? I'd appreciate.

Very nice! How many miles does this monoball lasts?
So the MHE kit with Lemforder arms is about $475.
If you buy the arms alone and let's say you want to use pwerflex bushings, it will cost around $375 give and take...

For a daily driver, how long does MHE monoball last?

They last until they don't, it's highly dependent on driving style. I've had mine for three years, almost 40K miles, and they're still like new. This includes a few track days.

The upside is you can rebuild them for about $50 in parts, so if/when they need repair, you're not out the full cost of the monoball.

Thank you... I was just looking at their site and their DIY guide on assembling one of these. I guess rebuilding it means you will need to press everything out of the cylinder shell and press them in again. Right now my front arms have no play in the ball joints at all but my thrust arm bushings aren't in good shape. I will need to find away to press out the bushings and press in the monoballs while the arm is still connected to the car on the ball joint side. One time I tried a loaner tool and didn't work for me...

You shouldn't have to press them out to rebuild them, my understanding is it's the ball and race that need to come out, but not the retaining sleeve. That's how it works on my monoballs, anyway. YMMV.

Why not just take the arm out and do it on a press? I mean, you should be able to do it with the arm in the car, but if it's being difficult, make it easy on yourself...

Right, those will need to come out... And I think the retaining sleeve or circular clip will stay there. I don't have a press at home... One day once I own a home then I'll buy this stuff what does YMMV mean? Btw, since the locking plate is screwed on, can you tighten it more when you start getting a little play in the monoball? Or they just need to be replaced?
Is nylon that much durable? Interesting...

On the Moosehead monoballs, yes, you're able to tighten it down to alleviate play up to a certain point. And Nylatron has excellent wear properties.

Your mileage may vary
