hi, i tried breaking loose the front coilover collar, not the ones to change the preload, but it's like stuck on there.. soaked with WD40 before trying.
Tried to break it loose with the hook (?) like tool (the tool that comes with the coilover) that is extended with a pipe.
This didn't work either. Hammering the end of the tool didn't work either.

The edges of the collar is kinda rounding off now..
How do you guys go about breaking it loose?
i have stance gr+

 

Have you removed the coilover from your car or are you working with it while on the car? Also, do you have 2 of the hook shaped adjustment tools?

 

the coilover is still on the car. i do have the two hook shaped tool.
the edge of these rounded off too..

 

Well I don't need to tell you that you fawked up. Take the coilover off the car, it will be much easier to work with. If the adjustment tools are still able to get hooked on the collars than try using a pipe on both tools. Lay the coilover on the ground and put your foot on it while pushing down toward the ground on both pipes.

If there is no way to get the tools to hook to the lock collar, than you will need to lock the lower seat in a vice and use a hammer and screwdriver to bang the collar loose.

Otherwise its time to bust out the cutting wheel and cut it off. Be careful not to damage the threads.

 

Tried and true method of breaking seized collars loose is a flathead screwdriver and a rubber mallet. Just don't go too crazy when you start trying to hammer them loose. I've also heard good things about PB Blaster.

 

This.

The "hook like tool" is called a spanner wrench btw.

 

I think you've done pretty much what should of loosened them up.
I have Bc Racing Br type, and after a year..they were a b tch to get loose.
Only thing different I used PB blaster and it took some muscle, and smash the hands a few times for good measure. Let em soak for awhile and get a strong friend aha.

 

i hope you know that one of the collars is reverse threaded too...

 

Although i tried, spanner wrench + hammer, i'll try the pb blaster and flat head+ hammer while the coilover is on the car.

i'm trying to loosen the front right side. Which way should the collar be turned? the one for adjusting the height, that is touching the bottom shock.

 

Are you certain about this?

 

There are no reversed threads. At least I've never seen coilovers with them anyway and find the idea of them a bit odd.

 

Aerokroil works great , I clean my thread every coiple months to keep them nice.

 

If you are looking over the collar, you should be turning it counter clockwise. Use the flathead/hammer method. Its odd that you tried all those things and its still stuck..

 

+1

Not aware of any reverse threads on coilovers.

 

Tanabe Sustec Pro-5 coilovers. When they came out of the box, both collars turned in opposite directions, making it appear as if one was reverse threaded. Maybe they just installed one on each strut upside down for no reason, who knows.

 

then i turning counter clockwise...

 

sorry.. i think i might have been a little tired and remembered that you have to lock the collars together by tightening them against each other. Confused myself haha sorry again.

 

if you cant get it loose with the hammer and flathead method, i would suggest putting a little heat on the locking collar, then use the hammer/flathead method. i use a propane torch i bought at home depot. a real helpful tool for the DIYer

 

op would it kill you to post a picture?

 

my 2c

1. Thread lock was used when installed
2. When installed the collar was tightened so tight that the threads on the collar deformed
3. You are tightening vs loosing

if the strut is out of the car you should be able to hold the larger collar with the C spanner with one foot and use the other C spanner and a rubber mallet on the smaller one. Undoing the smaller one should be easier than the larger one which has pressure from the spring.

Potentially try this:
