Best way to remove ball joints

Mr B wrote:They nothing unusual it just as nissan wanted sell whole arm & R not a big seller the bj got over looked in patern parts rather than not being available from manufacturers. I seen a few people say about welding & few not. is really down to what joint you get & the brand too as the spec size differs a little thus the interference fit could be too low in worse case scenario. I found brands like delphi & 555japan & Moog K9633 with no knurling spline on the fit area far better interference tolerance over real cheap monkey metal brands .
Basically OEM arm bore is 38.0mm, due to hole deformation/stretch from re-use & clean up from corrosion you need joint around 38.2mm minimum for good interference, Delphi TC600=38.2mm, Moog K9633=39.2mm will work if ream bore out to 38.8, they have grease nipple, innovative boot & very good quality, FAI SS1163 should work as well but not used or measured them .

much prefer the bolt on lower joints over press fit but they not used much these days as it all going towards full arm :-/ done ones on 206 hdi today what a cock those arms are hidden in the subframe  with bolts from top with not enough room to fully lift bolts without hassle, f00king french engineers :-S can work easier on an R with one arm than 206 with 2 arm :-P
