When I turn the wheel right & left there is a clunking noise off the steering. The steering rack is bone dry and the fluid was down approx. 20mm I topped up with rack sealing fluid but the clunk is still there and the fluid has not dropped. (2012 Multijet diesel 1.3 van). I also noticed a weeping of oil from the front bottom LHS (if sitting in the drivers seat), as I have spent the last 4 yrs trying to find a workshop manual on it I don't know what its coming from. I don't know if its a diff or a gearbox. Thanks, any help is welcome
