Lower control arm issue

If you've removed the bushing shells, buy a set of Peter Bergman's delrin LCA bushings. You'll still need an inner sleeve though if you reuse the stock pins.

I have yet to see a poly bushing that didn't need both the inner and outer shells of the old bushings to install. Maybe PST is doing something different now, but all the ones I've seen in the past need the old shells in place, only the rubber is removed.
