Ordered a new passenger side ball joint for my car which turned up this morning, took the wheel off etc to find that the orginal one is bloody rivetted on! Id had a look on google and it was adament that they were 3 bolts not rivets (now Ive found out thats on the later models only!)

Is it safe to take the wishbone off and grind the bolts out or is this not the case at all? I dont want to grind them out to find that its all pressed together!

Thanks.
