Default Jag 420 trailing arm removal from wisebone

Hello to you all,
It has been awhile since posting anything. I have just hit a roadblock and seem to not understand how to remove the trailing arm from the wishbone of the rear suspension. I have removed the NUT and I have removed the other end bushing from the frame. I do not see how with the NUT removed ,how to remove the smaller end. Let me post a photo or two .

Is the bolt removable somehow?

Looking at the parts on Moss Motors, I do not seem to have the same set up! Anyone else have this issue and if yes how was it resolved?
Thanks

Item 27 is a bolt that appears to thread into the wise bone.  That is not my case.  Any ideas !!

It looks like yours was installed backwards- the bolt head is stuck in the control arm instead of the nut. Have you tried tapping the bolt out of the arm? Possibly more pounding than tapping......

I have not tried anything yet Jerry.
I am hoping that someone has had the same issue and knows how to solve it.
I can only assume that maybe one end is threaded into the wishbone. Or it might be a press fit.
I do not wish to make it worst !

The nuts removed, then it should just slide out.
The bolt is rusted to the inside of the steel sleeve on the bushing.
If the bolt is turning, then the sleeve on the inside of the bushing has let go of the rubber and is just turning.

This is just me, but I would use an Oxy/Acetylene torch on the bolt to break the rust and it should just tap out.
The rubber bushing will catch fire, so do it outside.

If you want to try to save the bolt, you might put the nut back on loosely so that you are hitting it instead of boogering up the threads, just until it starts moving.

Hello Jerry,

Sorry if I sounded unsure of your reply.
I think you are correct and I have found another link elsewhere which addresses more precisely what I am dealing with.

https://forums.jag-lovers.com/t/help...-1-1966/363869

They suggest to put the nut back on and then insert a wide metal spacer between the end of the nut and the shock mount. Then unthread the nut and it should push the bolt out. I wil ltry this later and see how it goes.
In the meanwhile I have another crazy repair to do on my VW daily driver which involves removing the front seat and removing the upholstery. I have a bump in the seat back ......not comfortable

Thanks
Jim

The bolt is a special bolt, it has one flat missing to slide in past the shock mount. As mentioned, yours is in backwards. To remove this you'll either need to remove the hub carrier to hammer it out, or cut the bolt.

I assume the arm is coming off to replace the rubber bushes?

Hello all,
So indeed the bolt can be pushed out. I am not sure how it would work if put in from the opposite direction. Regardless, the bolt is moving and can be removed and reused !
It has been one year since starting to refurbish this car. I must get to the rear brakes, and to do so I have to remove the IRS system. Once I see all the parts that need replacing, that is what I will do! The bushes need to be replaced. The trailing arm itself needs repair or replacement. I will see if I can repair it, i.e. reinforce it. So onward I will go. Thanks for the help from all!
