The factory bolts come with their threads covered in Loctite-ish stuff (assuming they are identical for '40s and '300s, which they most likely are).

Too late to help you now, but for the following poor '40 owner who needs to this: heating the bolts before removing may do the trick...

I didn't see any loctite on the thread of the one bolt I've managed to remove but the bit that goes through the base of the ball joint was certainly very rusty and weakened, hence it snapped so easily.

What left of the original ball joint:

I've decided to tackle the snapped bolts today, of course easier said than done. For the past week or so I've collected the necessary drills and taps and thought about best approach. Packed all the tools into boot and drove to my friend with a better space.

That big blue case is a 100 drill set, after snapping and destroying about 5+ drills on the other side last year I thought these would come handy :lol:

I've removed the single bolt that was holding up the new ball joint. Clearly been pushing it... :roll:

Sadly the metal wire holding the rubber boot slipped from its groove and damaged the boot, so I needed to remove the whole thing and put it back in. Might need to replace the ball joint again at some point or at least the boot.

Then it was time for the snapped bolts. This method worked well:

Took approx 30 minutes to drill each bolt, the angle needed to be perfect because as soon as you hit the wishbone(which is made from adamantium) drill stops or gets destroyed. Tapped each hole and finally got all bolts in:

Massive improvement and I can finally drive safe :) Now time to do the wheel alignment.

While I had the car on axle stands I've also replaced the rear left parking brake cable that snapped last November. Replaced the rear discs too as its so much easier to adjust the handbrake with new discs :)

Everything took 8 hours but finally I've got a MOT worthy Jag again :lol:

Now just need to clean the interior, fit in recovered sunvisors and hopefully enjoy it for a while without getting the grinder out again 8-)

PS

I know I have to clean that spring pan at some point :oops:

A good days work there , drilling out those bolts must have been a nightmare but credit where it's due you persevered with it and succeeded ,

I took the car for its MOT yesterday and it failed on the driver side lower ball joint! :cry: Its the same ball joint I've replaced last October for the last MOT. While the car was on the ramp, the mot tester showed me how much play was in it and there was literally half an inch going up and down! :o

So I took it back home as I had a spare at home and fitted it in this morning but before I've managed to do it I had to remove the old one and that turned out to be a hell job :evil:

First I've tried to hammer it out for an hour but that just didn't work. Then, I've cut off the bottom of it to get better access to it, then tried to knock it again but no luck. I've decided to get the welder out and welded the top nut to it, then turned it a little and that did the trick. After hammering it for approx a minute it finally came out. Fitting replacement took 5 minutes... MOT passed.

My elbow hurts now, I feel almost like I've just changed the basterd hose... :?

Car failed MOT again on the same ball joint, three times now :evil: Half an inch play if you use a crowbar. What a pig to remove again :(

1m crowbar, lots of hammering it, nothing. Eventually I undid the nut almost all the way up and driven like this to pick up a halfords ball joint separator. Still nothing, didn't budge. Last year their ball joint separator bent but they didn't have anything better so slightly modified it and tried again, it started to bend a little again so turned to hammer onto the separator, few desperate blows and it finally shoot like a bullet. What a pig to get it out. Think I'll need to invest into a proper heavy duty separator. Took 3 hours to replace it, clearly 12k miles on Cambs roads is excessive for these :roll:
