Feedback on Midolyne Strut Rod Bushings

basstrix · Sep 19, 2024

The rebuild kit I'm installing came with Midolyne strut rod bushings. I've read mixed reviews on these....seeing where some have experienced them splitting/cracking after very little use. They are supposed to be a compromise between rubber and polyurethane. They seem fairly soft to me.

I'd like to get feedback from anyone who has used this material for strut rod bushings. How did they hold up and did you have any issues, at all, related to them.

Thanks,
BT

Not only did they crack and split, but the stiffer durometer meant the strut arm was flexed until it broke, which only happen when driving.....ask me how I know.
I wouldn't use anything but original type bushings in that location on a street car or get the fancy strutrods that eliminate bushings.

A good investment here is to use one of the clevis or dry bearing rod options.

Did you ever run polyurethane bushings on those rods? The bushings I have are nowhere near the durometer of polyurethane.....they actually don't feel any stiffer than OEM rubber.

Nope. It was a friend's car. I did a front end rebuild on it. It was not even a year and the midolyne began showing cracks. Another year or so and the strutrod failed right behind the bushing.
I have heard/read of others having failed strutrods with urethane. Limiting suspension travel helps as the flexing of the rod is probably near the maximum angles of movement. A lowered, stiffer suspension on smooth roads might be fine.
