...point where the control arm attaches to the axle?

Only for a few moments until I can slip a jack stand under the axle.

Will the bolt holding the control arm snap like a dry twig? there is no rust what-so-ever.

 

I have jacked it up there,but prefer just under the ball joints,or the diff.

 

The OEM control arm is pretty thin.
Use a floor jack just to the left of the pumkin and take the entire axle up.

 

OK I thought it would damage the ball joints but if not I'll jack there, thanks.

 

I always use that point to jack up my XJ. If it can handle getting beatup by the road slamming up against it all day with a lift on it then it can hold up your XJ VIA a jack.

 

jeez balljoints?

i always use the control are bracket on the pass side and the pumpkin then put the stand on the axle in the lca mount on the dirver side
