Any advice welcome regarding seized air spring screw

Hi guys,

I started tonight the dismantling of different parts to remove the front lower wishbone as I wanted to replace bushings.
Everything has been removed in that area. Job was easy as replaced the lower ball joint last year (clunking is still here!).

Only both wishbone screws and air spring bottom screw are in place.
1 wishbone screw will probably require use of saw and second looks OK.

Problem is that bottom air spring screw is seized in bushing. I already pressed, pushed, hammered and empty a bottle of WD40 but nothing wants to move.
I can use bigger hammer and tools but I will probably damage the bushing or something else.

Do I missed something? Any advice would be appreciated.

Thanks. Disco 3 SE-MY2005 manual

I changed airsprings recently, and that bolt was very tight indeed. It took a large breaker bar to get the nut to move. Once the nut was off, and a bottle jack used to support the bottom of the airspring, the bolt came out easily.

You have depressurised the suspension first I presume? if not, the pressure in the spring will be clamping the bolt. Undo the the top air connection to release the pressure.

Thanks Gareth for your help.

I will try that!

It's like the inner parts of the bushing is rotating (some degrees) with screw that's why I thought that everything has seized. Disco 3 SE-MY2005 manual

Hi,

Screw is definitely seized in bushing

Inner part of bushing is moving with screw when rotating it so I stopped job and will reassemble everything.

Strange that lower air spring bushing is not mentioned in parts list as the one for coil spring is available?

Maybe I shoud buy new air springs to get the bushings

Now question is: are they similar and can I put a bushing from a non-air spring shock absorber? Disco 3 SE-MY2005 manual

Hi Stemu,
if i well understood you were working to change the following bush:

Am I right ?
did you solve the problem ? did you find the bush/silentblock? do you have the code of the part?

Thanks for your help!
