Update
Decided to put my 6' newt on the mount and see what the pec looked like with significantly less weight on it and it behaved perfectly. If you compare the attached screen shot with the one one this thread

It sure doesn't like a weighty 10” meade sct on it. The meade's about 12.7kgs plus 9.5kgs on an extender bar. People have run heavier I'm told but I'm probably pushing the limit. What do you guys think? As for the bearings, I was thinking maybe one of the rollers had failed and that gave me the jerky feeling and with my luck when I opened it I wouldn't have the bit I needed to fix it on hand so I bought everything in sight!!
Cheers
