Who has installed Megan Coilovers?

[03Z33]

I'm trying to upload the picture from the repair manual right now.

You must have the strut bearing and the nut tightened onto the strut before installing the upper rubber portion and before installing the strut into the car. There needs to be some preload on the spring (or at least the ability to preload it).

From the picture it looks like the stock strut bearing may press right into the red anodized spring seat? If so, then you should be able to tighten the nut up to the bearing before installing into the car.

I had originally used the entire seat from the OEM strut. Is this not correct? How do I get just the bearing off? That'd make some sense. Currently, this is what the assembly looks like (gotta love MS paint and that fact that I haven't taken any photos of the actual setup yet):

I would think the stock spring seat won't fit, so you'll need to press out the stock strut bearing from it and transfer the bearing over to the new coilover. If you can't push it out with your fingers, then try tapping on the outside race gently or a wooden hammer handle should do the trick. Then the nut (which I don't see in your diagram?) will go over the bearing before the rubber part (which fits around/over the strut bearing).

Correct. However, the first time I attempted to install this, I actually used both the stock and the Megan tops bolted together with the bearing and everything, and the pistons still came way out from the tops of the strut towers. After calling Megan, they said I am only supposed to use the red tops that they supplied. There was no mention of the strurt bearing, though.

Okay, assuming I need to take this part out and it does fit the Megan units, how much do these need to be preloaded?

Yes, you must use a strut bearing always on this type of suspension.

According to the repair manual the torque on the nut directly above the strut bearing is 25ft/lb. I usually use an air tool on it, but you don't want to over tighten it so you don't damage the bearing.

That is the way we did the installation. I'm not sure if we needed the bump stops (not used) inside the oem rubber.
