Hi Pat,
I was puzzled myself the rear wishbone bearings when I had to remove hubs – they certainly didn’t appear to be tapered roller as per Jag I.R.S. ( insufficient diameter within housings and nothing was inclined to fall out when hub assemblies were removed). I suspect they’re caged needle roller, but overhaul of the outer bearings wasn’t my reason for removing hubs, so wasn’t tempted to delve too deep into type of bearings used. I was more concerned how to get the hubs back on the car – they were a tight fit and had to make up a spreader to ease the wishbone lugs apart.
Couple of points – you’ll need a hub puller to get the hubs off drive shafts and the nearside drive shaft nut is left hand thread.
Hope that helps a little.
Merry Christmas,
Max
