Hey guys,

So the marathon continues and I have torn down the suspension to rebush the control arms and install some PSS10s

I have mode camber plates/top hats on the RSR coil overs which I will be moving over to PSS10s.

I am trying to determine the condition of the monoballs in the camber plates/top hats. I called mode up and they said I can send them to them and they can replace the monoballs with new ones.

When do you replace them as I know they are a maintence item? There is only 10k miles on them and most of them street miles.

Pics so you know what I am talking about.

Thanks!

The wear part is the Teflon belt seen in the one on the left, They'll rattle when it's gone


To get at it remove the nut on the end of the shock, I use a pass through socket and hex wrench for the shock rod itself


Then the large nut and bush, the Rose joint will now be free


mono-***** come w/ varying degrees of quality the best I've found are FKSSX16T, I get them at the local industrial bearing supply house,

Thanks Bill. Do you know if the front and rear ones are the same bearing?

In terms of wear, what I did before pulling the shocks out was yank on the shock in different directions with the suspension at full droop. I could not feel any movement so from that point of view "tight". It was not until I removed the shocks did I notice the top hot flopping around when I would shake the shock. The monoball was unable to "hold" the top hot at in position.

Time for replacement?

If you upgrade to the original OE Rubber hats they are good-to-go for 100K miles. ;-)

With the suspension at full drop, lift up on the control arm. You will feel a small axial movement if they are worn.
When I changed mine they had 5 thousandths wear.
Front and rear bearings are the same.
The FK bearings Bill posted are the best.

Hey Mike good to hear from you.

Thanks guys!

I called mode again and they said they can R&R each plate with a FK bearing for $50. Each bearing is about $50 retail so looks like I will send them out and not deal with the headache of a diy.

50 bucks is a good deal to just not have to deal with anything beyond shipping, but if you have a press,
rennline sells the fk bearing in their plates for $35 each. probably the same part.
or type the fk part number stamped on the bearing into a search engine and you'll find other purchasing options.
I bought them for my rennline plates 2yrs ago for $18 each from some volvo performance shop that came up in a part # search.

I fiddled around with a set of 993 camber plates for a 993 buddy earlier this year and found that I could remove the monoballs without a press.

Thanks. I zoomed in on the rennline pic and the bearing model number is COMH16T. Spec appears to be a 2" OD bearing whereas the FKSSK16T a 1.75" OD. Too bad as those rennline bearings are much cheaper!

No press needed for the bearing. Loosening the nut can be a challenge.

Hey guys,

Tonight I was able to remove the big @ss nut from the camber plate/top hat. I picked up a socket to remove the nut with my 1/2"breaker bar. Once the nut was removed, the monoball easily came out. Called mode again and they are sending me replacements without mailing the camber plates/top hats out...

I noticed FKSSX16T has two fitment options. F1and F2. I read F1 fits tighter.
What are people ordering? Thanks

In your shoes I would kick those things to the curb and go stock top hats. I am not shy about improving suspension components (solid subframe mounts, front LCA poly, solid rear toe link, RS rear bushings and RS engine mounts) but that’s one area I welcome the isolation of rubber in a street car. I just don’t feel the trade offs are worth it. Check with Rob at SCARGO and you’ll find a box full of monoball take offs from people who reverted back to stock.

i'll probably need to do this at some point too
