Hello All,
Looking for some input on suspension adjustment.
I have been trying to adjust my front suspension, but I don’t see anything happening.
WTF?
I am turning (to the right to raise, as per WSM) the adjustment nut on the shock but see no rise, or fall of where it’s sitting on the actual shock cylinder. I know that one rotation does not move the suspension much (about 1.5 mm), but I have spun my front left nut 12-13 full rotations and see no movement anywhere on the actual shock body. If things were as I thought, with 12-13 turns I should see a suspension lift on the front left of almost 20 cm! I made marks on the top of the lower spring plate and the bottom of the adjustment nut for reference.
Cosmo has given me a lot of input, thanks Ted, and thinks that there may not be a visible movement on the shock cylinder, but I thought I would ask here to see if anyone had, as the Terminator says, “detailed files” on the front shock assy.
The WSM makes reference to the Bilstein setup (I have OEM BOGE), and spinning the adjustment nut to max low, and then having free movement. I take this as spinning the adjustment nut full off the threads on the shock. Perhaps this is what I have, and the tension from my uncompressed spring is stopping the adjustment nut from getting back up on the shock threads?
Anyone been here????

Sounds to me like your threaded section is spinning on the damper body?
Are you sure you have stock equipment? – The stock damper is shaped to lock into the threaded section to stop it from spinning but a lot of after-market dampers are just smooth and the threaded section will just spin on them.
When I fitted my after-market dampers I had to glue the threaded section to the damper with epoxy resin!
If your PO has fitted after-market dampers and not secured the threaded part then this could be the cause of the problem. Also if the threaded section was not properly greases ,when fitted, the adjuster ring will easily rust solid to it which would make the problem worse.
I’m afraid your only solution would be to remove the damper and put things right.

these shocks may not be adjustable.
My suggestion toss them out and buy a set of bilstiens, they will come with new lower adjustable perches, and they are better shocks

I changed out all my shocks and the fronts were bilsteins. If you use Bilsteins just know they are stiffer than the Bogies. I actually liked the Bilsteins better. Did you take the weight off the wheel when you tried to adjust the nut? Mine wouldn't adjust with the weight on the car. I had to jack it for it to rotate independant of the sleeve. I just changed my shocks and springs so my sleeves are greased and I still had the same problem with weight on the perch.

Hey Mike
12 - 13 turns should definitely give you some lift. I agree with others here that the sleeve is spinning on the shock. It looks like you have the standard gray gas charged Boges but you never know what a PO has done.
Here is some info from my WSM showing the exploded view of the Boge adjustable shock. A note for item #12, the threaded collar says to install it with the bevel facing down. Perhaps it was installed upside down?

Sounds like your sleeve may be frozen to the nut.
I've used an exhaust pipe expander to grab the sleeve so it can be broken loose. AutoZone will let you borrow one.
The non-adjustables look differently.
