Front Lower Ball joints

[jimmy1945]

I am currently rebuilding my front suspension on my 1990 XJS v12, am i correct in thinking that due to the ball joint having a tapered shaft you can tighten the nut to its maximum or is there a limit on how much poundage you put on it.

Hi - there is a torque setting for this but I can't remember what it is off the top of my head.
As a safety related component I would be inclined to tighten it to the correct torque. Too little and it may work loose and chatter, ultimately falling off I guess although you should be using a new nylon nut which should prevent that. Too tight will put excess strain on the stub and it may fail with obvious dangers.

Thanks David,
I am using a new nylon nut so it shouldn't work loose, do you know where i can find out the torque setting please.

Hi - I just looked it up in the Repair Operation Manual and it should be 55 lb ft or 75Nm
Hope that helps
