Mine aren't self levelling Chris 

[YZ250]

............

Two more quick Q's if you don't mind:

1.) I remember last week removing a damper and the I couldnt get the bloody thing lined up at the bottom so as to get the bolt through. Am I going to run in to that difficulty again?

2.) The new shocks come with a small metal cylindrical object.... I'm thinking this is an insert to go in to the bottom bushing. Would you concur?

Cheers.

I find it easier to fit the bottom bolt first and then aim the top through the hole in the boot floor as I lower the car, but I have an estate so maybe the boot carpet is easier to lift up for me. 

Could this cylindrical part be a new spacer for the upper buffer.

Ah. Ignore the air line bit in that case.

[Webby the Bear]

Thanks guys.

I'm just going to follow the guide.... prime new shocks, fit bottom bolt, jack up til they're in position, do top nut up.

When I get home I'll whip them out and have a proper look. I'll show you a pic of everything and see what you guys tyhink

Yep

[Webby the Bear]

Right then girls....

Here's the make of my new shocks:


Found out (as someone quite rightly said) that the cylindrical object goes in the big rubber bush at the top...


Here's the top of the damper and I cant see a nylon thread to unlock

[05omegav6]

Not a nylon thread

GM ones come with a nylon binding band that runs from the top of the rod all the way down one side, around the base and back up to the to. This keeps the rod compressed... it's the same stuff used on boxes to stop them coming undone

Yours are plainly different.

[chrisgixer]

Something isn't right with those.

Left to their own devices they should extend, fully, on their own.

They don't appear to be bound with pallet strapping (as Gm self levellers are out of the box) and doesn't appear to be anything stopping them extending to full length as they should for fitting.

I wonder are they faulty or incorrect for the car...?

I'm hoping it's like at 11m 20s in this video....

Ok, I can pull the metal shaft out but when I push down they don't come back up again???

That's not right, ime.

[Webby the Bear]

They've got resistance.... they just don't ''spring'' back up like in the video

Traditional shock absorbers are filled with oil & a bit of air. Under hard use air can mix with the oil which upsets the damping action.

Gas filled shock absorbers have gas under pressure above the oil instead of air. The increased pressure reduces the effect of any bubbles but requires better quality shaft seals to prevent the gas escaping.

The gas in gas filled shock absorbers is under high enough pressure to extend the shaft, traditional shock absorbers are not pressurised so do not extend themselves.

I think the shock absorbers you have bought are 'traditional' and not gas filled like the originals.

Thanks Andy. 

I will fit them and hope for the best. The fact they don't spring up by themselves means (touching wood) they should be a bit easier to install.
