Hi

Does anyone know if there are any grease nipples anywhere on the steering column of a 1999 VW T4 manual 2.5 petrol? I have been getting a squealing noise coming from the steering, it only happens occasionally and only when stationary or when pulling into/out of a parking space. It also happened when up on a hoist at the mechanics while doing a major service, he was surprised and he didn't know what it was. I googled but could find no info on greasable joints or nipples.
Any help would be appreciated before I take it back to the mechanic for an explorative and possibly expensive visit.
thank you. steve
