I’ve been replacing all of the engine mounts in my 2004 XC70 and the lower bolt on the rear lower engine mount is giving me a horrible time. I’ve tried using a swivel socket and an extension but there is a bar getting in the way of the extension and the swivel is not enough. I was thinking of using a crows foot or some other tool to get it. If any of you have any advice or experience doing replacing them let me know if you have any tips or suggestions

 

I ended up enlarging a hole in the subframe with a stepper drill bit to about 1/2 to get a 3/8 extension through and using a 15mm swivel socket to get at the bolt. I was desperate at this point after using a bendy extender and bending it permanently. I’m going to put in send over the exposed metal to make sure it doesn't rust
