Hi Tony
It can be difficult. A mechanic colleague bought Javelin fwbs SKF brand from a major supplier. Failed even sooner than normal. Turned out fake. Some years ago the mainshaft bearings in my wifes Sentra failed woefully. Had never tackled a modern so replaced diy.All the bearings were Jap except the most simple dead common one, which was Polish or some such. Failed in about 25,,000 miles, although the buyer did not twig.....(incidentally the local agent said they used the cars to train appentices. Had repleced several hundrd pinion bearings! The rollers were hugely reduced in dia and the oil like silver paint but not esp noisy.)
And for anyone tinkering with Sevens, trailers etc have to be on alert for ac races where not intended (or fitted reversed!)
