Well I am pleased some of my advice was useful to you.Hi Anaconda
Thank you for suggesting to use a NAK driveshaft seal fitted one today and the problem is now solved!!! What a relief the NAK seal is a lot tighter to fit and also tighter on the shaft don't use OEM or genuine they're crap! As I found out I would also like to say a big thanks to all that replied to my problem
Cheers all davethebuilder
Out of interest what did you use to knock the new seal in.
