Hi guys,
Firstly - can I send best wishes and support in our thoughts to any members in Texas and Louisiana and others affected by the floods which we in the UK are watching closely.
So... (and probably not that important in the great scheme of things) I am taking the front suspension/brakes on my 77 A2 apart to clean, blast, paint and renew where necessary. The vehicle is on its rear wheels with the front wheels, brakes and hubs removed and the spindle support and ball joints in place. It is on stands under the body close to the front bumper.
The plan is to disassemble down to, and remove the front suspension cross member. Going with TM 9-23200218-20 removing the shocks and the springs looks simple. To take out the springs the manual says to support the lower suspension arm with a hydraulic jack and says to remove the bottom nut and washers on the shock and the oval shock mount. With the shock now free I planned to drop the lower suspension arm, take off the top shock nut, and take out the shock along with the spring. I have got as far as being able to remove the bolts holding the oval shock mount and turn it to face the opening beneath - but the nut on the bottom of the shock will not turn without turning the shock body.
It could be seized - it had surface rust and a thick layer of underseal. This was removed, the nut and thread below was well wire brushed and the joint between the nut and the suspension arm was cleaned out with a dental pick and my favourite penetrant release liquid was applied. IMO the level of rust was the same as all the other nuts which turned today using the same method - but this darn nut still turns the shock body!
Going back to the manual I see the specific method for removing the shock says the vehicle should be supported at the front but does not mention supporting the suspension arm with a jack or removing the lower ball joint as per the spring.
So, is it a question of the loading/unloading on the suspension being crucial for removing the shock and/or the spring?

Re: Front shock removal
I'd use a spring compressor, I would heat up the nut with a torch

Re: Front shock removal
I had the same problem on my 73 A2. It sat outside for a while and the whole nut was rusted together with the shock.
I went the brutal way and caryfully cut the nut in several places until it came lose.

Re: Front shock removal
The shock usually has a hex on the end of the shaft a wrench fits on to hold it while you turn the nut. If this hex is not there or rounded off then splitting the nut is about the only choice. There are a lot of tools out there just for that job, just Google "nut splitter".
Here is just one of them, I have used this one in the past with good results. I also have a OTC one.
