Quite a few years back a friend of mine happened upon some off brand turbo tie rods on eBay. They were $80 a set which was hard to pass up.
The following started to happen about 2 months after installing them. They are shown beside their Lemförder replacements for reference.
It's fairly obvious that the rubber was missing a key element of ozone protection (antiozonates). This is what everyone means when they attempt to steer you away from cheap turbo tie rod alternatives.
These were never in use...
