Default rover 75 rear upper supension arm

hi to all
this is an update to a previous thread I was told that the captive nut could fail if seized and the subframe will then have to be taken off so I had this idea I made a tool to support the captive nut and it can be fitted from underneath from the passenger side there is room for you to fit the tool see photos my welding is not that good so please ignore I hope this will help

David, plenty of plus gas, tighten the bolt first, then slacken.

As soon as the bolt starts moving, change from 1/2" to 3/8" drive sockets, this gives you much better feel for what is happening.

The trick is, if the bolt becomes tight while being slackened, stop and reverse the ratchet and tighten it again, and plenty of penetrating oil squirted on the end of the thread.

Working the bolt in this way reduces exponentially the likelihood of the captive nut bursting out of it's cage, if you attempt to wind out the bolt in one go, it will almost always end in tears.

This is more likely to help you than your tool, which would be almost impossible to position to support the cage of the captive, and even if positioned perfectly, the arm of the tool is 90 degrees away from being useful in preventing any rotation
