Im trying to get the cone compression tool down the top to screw in and it doesnt seem to want to grab on anything. All i can see in is these 2 photos but i have no idea how it should look? Could someone please give me a idea if this is right?

Sometimes the hole/thread can get really ugly, so much that it can be so full of rust and sh*t that a thread tap is required. this presents problem number 2, get a tap down there. You'll need to braze one onto a bit of rod with T on top.
Might sound a bit rough, but usually when they're this bad the cone is stuffed too, I get stuck into cone/trumpet with an air chisle then bin the whole lot. Are you fitting hi lo's or something?

I only needed to compress the cone when i put the new ones in

If you have no air chisel an angle grinder will do. :twisted:

I did mine recently and only needed the compressor when fitting in new cones.

Remove that square rubber stop for some space as top arm has to come out - check condition of pin and bearings. Lever pin from front. Change the knuckle joint too if needed.

Other than cone compressor, you may need a ball joint splitter.

If you want to replace the top bearings, they are a bugger to remove. But I have a new puller that works, bring em over.
If the top shafts are not worn, keep them. Their material & hardness is way better than the aftermarket ones being sold now.

Both pins/shafts and bearings were good doc.

Just to clarify stib, top arms gotta come out for new stuff to go in.
