In the pics above, the rusty rack is the original for my car. It has been sitting outside in the weeds for several years. The pic looking at the end shows that bushing dissintegrating into what looks like cork crumbles, and the last pic shows the retainer washer that holds the bushing in,and it is covered with the "crumbles". So, the first two racks had similar bushing failures, but we don't know what the bushing material was. I now have #3 rack, from the same manufacturer installed and working fine, but for how long ? We (MG guy and me) pulled the r.h. boot on the new one to see what the new bushing looked like, and it was a dark grey plastic of some sort. I'm going to take the original rack to the MG guy (Glenn, of Glenn's MG Repair ) and see if he can go back to his supplier to try to find out what the bushing material is, and if it's been changed in the last few years.
I'll report back with any findings.
