Default V70 Ball joint rubbing against rim

Hi,

Rubbing got worse over the week, found the place where the ball joint rubs against the rim, may happen when turning right. Not driving until fixed. . .

Recently replaced: CV axle, wheel bearings, inner&outer tie rods, sway bar end links, ball joints

Is the ball joint not tightened enough? Why would it start sitting lower? Should I try new ones? Rims are 15", so possibly have the smallest/worst clearance situation

Old stuff include control arms and struts. Strut upper bolts are springy on top, and control arms were tight when last tested.

I suppose a board rule about preventing a "non-expert" from answering first would be helpful...but here goes.

Remove the wheel and take a grinder to the edge/protrusion which contacts the wheel.
Hold the grinder at an angle which matches that of wheel's inner surface where scratched.
It doesn't seem to contact the wheel that much, ergo very little dressing will be needed.
Such dressing won't effect the removability of the nut and stud.

Off the top of my head I'll guess an aftermarket ball joint with a longer-than-usual stud was installed.

What make is the new balljoint?
I'm guessing that it's not genuine Volvo, Lemforder or Meyle.

Also, how did you cross reference part numbers to be certain of a correct fit?
P2 Balljoints can be different shape dependant on model year.

To me, the length of the ball joint looks pretty standard - including the remaining threads near the bolt, see the link below. The struts or control arms have nothing to do with this clearance. I assume you use genuine 15" wheels ? I also have the 15" and there is about 1" clearance to the stud of the ball joint.

Looks like you replaced the whole hub/bearing with used parts. Were these from similar V70/S60 ? If you still have your old parts, may be worth comparing the dimensions

The fit is for the old aluminium control arms with cone insert, these are by Quicksteer. I believe the CV axle was SKF and other things were SWAG.

I compared all parts with old ones before installation and they were identical within a millimeter. All replaced ones are new, replaced 2 weeks up to 3 months ago so some grime is already on.

Thanks. I wanted to prevent grinding as I thought it would mask a fundamental issue somewhere...

The hub assembly was new, matched with the old one. I have been a little puzzled as to what exactly determines the center of the wheel. . . Can coils sag by 5 mm to affect this?

These are rims that a similar size to original ones, my winters are originals but they are out of reach to compare at the moment. . .

No, the wheel is attached to the bearing plate (the one with the 5 holes for the lugs). And the bearing with it's plate sit inside the hub (spindle)

The coils will affect slightly the 'angle' of the control arm and rotate slightly the ball joint stud, but again, there is so much clearance between the tip of the ball joint and the wheel that I can't figure out what would cause this gap to vanish..

I've reuploaded my picture with a zoom in

Now not all 15" rims are the same.. the offset may be different, and the inner 'clearance' of the rim surface may not be the same. from your picture it is a little difficult to say but it looks like the surface of the rim makes an angle going towards the center of the rim. My genuine ones don't make such angle, the inner surface is 'flat' - the 'inner' diameter of the rim is the same across the section of the rim

Thanks for the nice picture, I showed it to the mechanic. They basically inspected the whole front end. The ball joint cones were found to be very slightly different, so the ball joints are now Meyle. I'd say they added 1 or 2 mm of free space, at most. Everything else was top notch. They did another alignment as final step. The rubbing is mostly gone, but it is still close enough that I think it still knocks sometimes on sharp turns over bumps. I guess I have to put bigger rims to get rid of it. . .

Are these aftermarket 15" rims?

Yeah, could be Alessio (hub caps are Volvo ). As I recall, the original 15" ones were indeed flatter inside. People have historically opted for larger rims here, so this problem seemed obscure to everyone.
