RPM BallEnds

[jo90]

I've bought a set of long RPM ball joints for the DEX210 as recommended by a few. Tried to fit one lot last night on a camber lik and they are so tight the arm wont move

How have people used these and managed to loosen them off enough to work and yet be practically tight on the Durango ball joint ?

I didn try pinching them with pliars and also working them around the ball end with some silicon lube between them to stop to much heat build up, still no joy

Help as always is appreciated

I think you need to use different ball studs as well? Not sure which as I run kit but I'm sure I've read that on here somewhere...

Have you changed the ball studs to suit - it doesn't sound like it?!

You can't leave the TD studs on the car & use RPM joints - unless you like them very tight!

You need ~4.3mm studs like the schumacher or HPI ones

I did work out a list of what was needed to do the 210, but i lost it.
I used the Team Associated Ti Ni metric ball studs. Bit on the expensive side, but work well (so far).

Yupo, but there are about 8 different models, 3 or 4 different thread lengths and then long and short neck. Took me bloody hours to work out!! And i got it wrong first time, so the list i have in the back of my book here won't help.......

[NeilRalph77]

I just got broached longneck 10mm thread length originally only place you need a shorter thread is on the steering rack but i just shortened the 10mm ones. short neck are for horizontal applications but it was just easier to but 2 packs of one than as you said 1 pack of 8 different types.

AS31285 I believe they were.

Ahh, yep im using the durango studs ! DOH

Right I will look into some different studs...my poor wallet hehe

[jo90]

Can confirm the HPI 4.3mm and the TOP titanium 4.3mm one's fit perfik

You just want to be careful when you remove the RPM ballends since they are such a tight fit sometimes they can get damaged while trying to remove them, if you have to do maintenance.

I tend to use them (almost) as single use, if they need to be taken off, they go in the bin. At about 4 dollars for 12, its really not worth mucking about.

(OK, maybe i'll pop them off/on two or three times then chuck them in the bin......)

[jo90]

i've drilled the ball cup top so you can put a driver through to unscrew the ball joints so no need to pop them off

I find using a set of circlip pliers and slide them under the ball cup, avoids twisting them off whihc causes damage.
