Rear top mount removal

[s.mac]

Anyone know how to remove a top mount so I can add a spacer spring ?

From the top.

You remove the carpet and unbolt two bolts.

Take the shock off
Takes 2 secs as you know.
Then there will be a nut in the middle of the top mount, undo said nut, remove top mount, fit spring, refit top mount, redo nut, refit shock.

Easy enough for you steve:finga:

Nice one Lawsy, I know it's a quick job as its been done a few times LOL
Just wasn't sure on the last bit, it wants to go down a tad and AST gave me the spacers just in case, so the spring doesn't rattle around.

The spacer ring is actually an assistor spring, they assist the spring in locating correctly and stop it rattling around. I assume you also have a small spring platform to go between the assistor and the main spring to locate the 2 together

add: ive just looked again and you already have one of those fitted to the pictured shock absorber fitted at the bottom so why would you have another ??

Steve, Equinox has raised a good point, you shouldn't need two sets of helper springs on your shocks.

Looking at your pic he's quite right, you already have a helper spring at the bottom.

Did AST set your preload before letting you drive away on the car?

Pre load?? No idea what this is mate
I was going to drop it a tad and they said if I did I might want to put them on?

[Equinox_csl]

You wont need to fit them as you already have some, even if you drop it loads you only need one assister spring.

I'm going to the garage tomorrow and will take a better picture.
I haven't lifted a finger today, I've been badly after a very very, VERY heavy night.....
I can always contact AST , the tech who fitted them said if I did want to drop it down I should fit the spacer spring to stop it rattling as the spring wouldn't be tight, if that makes sense

[Equinox_csl]

The spring will only rattle when either the car gets light, air or a lot of weight transfer to raise a certain corner enough to take all shockabsorber pressure from the spring. 90% of the time it'd be perfect.

Thanks :thumbs:
I was only looking for something to do while the wheels are off

The lower spring looks like a proper spring and not a spacer

[Equinox_csl]

The lower spring is an assistor spring designed at a lot lower poundage than the main spring so it sits totally compressed when weight is on it and will extend when the suspension is 'light' in order to keep the main spring in place and stop it rattling around, it needs to be a spring then it can extend as expected. If you didnt have those the spring could come out of the top spring cup and when weight is returned the spring may sit out of the cup or be noisy when going back into the cup. The assistor spring keep enough pressure to keep the spring in the top seat / cup at all times

cheers
I'm going to leave it alone
