Front suspension question - rubber dust covers for struts...

I'm rebuilding the suspension on my Targa and needless to say I slid way down the slippery slope. I'm shedding the original metal dust covers looking to replace those with rubber bellows. I see that others have done something similar.

I acquired some boots which presumably would attach to the lower body of the strut (below the gland nut) and attach to the rod up near the upper strut mount.

Question: How do you deal with strut rotation during steering? Does the boot just twist? Or does one end need to slip/rotate?

with the accordion nature of any rubber dust cover you might implement as long as they are secured well both top and bottom, not fitted to tightly steering range should be of little consequence.

caster steering angles are less that *45 on full lock in our cars. the rubber should twist accordingly,, pun intended...

Thanks. I might be over-thinking this (and it is the reason I'm asking) but I've never seen a rubber accordion-style bellows do well with torsional displacement (they're made for axial displacement).

After thinking about this one for another day: Has anybody made anything like a carrier bearing to place at the top of the strut so the bellows doesn't have to rotate? (There I go overthinking it again...)

Only photo I could find:



Generic 4x4 dust boots. I don't even have them zip tied anymore. Mine don't get sandwiched between the strut top and the camber plate, so they are free to rotate there. Pretty soft / squishy rubber so they rotate pretty easily anyways. Aka, you're overthinking it.

There's a VW boot from a 2000 generation Jetta that fits fantastic at both the top of the damper shaft and the bottom of the strut body. I've used these before and I just left the boot loose at the low side.

It's part number 357-413-175-A-M36 and you can get it here from Pelican. $4.25 each for the Febi Bilstein brand and there's three others to choose from- Genuine Audi VW, Meyle and Rein
