Mystery of the day.

Post by RollyTG »

I am in the process of replacing the RHS rear suspension mountings and encountered this mystery on the rearmost one. The bolt appears to have been inserted the wrong way around by some kind of magic or ancient British druid wizardry.

On all of the others the nuts are on the inside - no problem. There appears to be no way to get this bolt, or its mate, out. Cutting them off seems to be my only option. Any suggestions or illumination welcome.

The rear mounts are held on with two bolts (the ones you are trying to remove) through the chassis leg but they are also held on to the subframe by a single studs with a nut on. You can get to the nut and by removing this the mount will come away from the subframe leaving it attached to the chassis leg. Once the Subframe has dropped you can then remove that bolt which has been put in the wrong way.
I would suggest that someone has had the subframe off previously and attached the mounts to the chassis first then offered up the subframe to the mounts.

Below is a photo of the subframe mounts showing the bolt holes at the top and the single stud at the bottom.

Not the best photo of the rear subframe out of the car but the only one I have. It shows the mounts still attached to the subframe and give you an idea of where the stud nut should be.

Thanks for the rapid response. Pondering on this over a cold beer (it was about 95 degrees in the workshop today, so I quit early ;-)) I also came to the same conclusion - that the mount was bolted to the chassis and then attached to the subframe by the centre bolt. I did the two on the other side a while back and did not have this problem. Those two were totally shot but these two are not quite so bad. As well as the single central bolt which attaches the mount to the subframe, my mounts are also attached with two other bolts through the "ears" on the mount. I presumed that was normal. Am I mistaken? They are right royal pains to get to. I don't want to take the rear suspension out until I get the car on the lift in my new garage (which is right now under construction) but this should be doable without taking it out. Thanks again. But for a problem with the transmission shifter linkage, I am almost ready to be on the road.

Mine are only attached by the two chassis leg bolts and the single stud and nut. You will have to post a picture of what you mean. If you put bolts through the ears as you call them they would not attach anything as they are below the chassis leg but above the subframe.

There are a number of locations on the Mk2 & S Type where the nut & bold require the correct location. More so Mk2.

Here's a couple of pictures showing where the two "extra" bolts are. It's all out now after much levering and some grinding. I will get the new ones in tomorrow maybe. Thanks again for the advice.

And here's a picture of an XJ6 rear suspension unit which shows one of those "extra" bolts I was dealing with. Looks like I should put them back in.
