Hi everyone

The above vehicle is suffering from steering jamming on a slight lock then freeing up. The steering rack has been renewed twice, the Pas pump has been substituted and pressure checked ( readings compared to another C Class).The steering column UJ is smooth to move in all directions. Lower Ball joints check out all good, front shocks, coil springs and top Mtg's are all new from a previous job. If anyone has experienced this before any help would be appreciated.
