Ok I just installed some new kyb struts on my car and I. Neglected to tighten the top bolt while they were off the car.

Now I know the procedure of tightening the bolt while they are on the car but my question is this :

How much am I supposed to tighten them? I noticed when I press down on the car the shaft comes up a bit more which in turn leads me to believe that it needs to be tightened more.

Am I right?

I have about 4 threads showing on bolt but It still appears that it should be tightened more

Thanks in advance

Pics for reference

 

Isnt that to set dampening rebound so soft to firm

 

I have the slightest idea lol. Maybe someone else can chime in. I'm guessing the clunking I'm hearing on large bumps is because the top bolt isn't tight enough

 

Anyone willing to confirm this?

 

Call kyb

 

Yeah you need to tighten them more. The KYB have no adjustable dampening. Just impact that bolt on there, that's what I did.

 

Ok great thanks. I'll tighten them in the am. Will it eventually stop tightening? So I can know when to stop lol

 

I am running KYB also, and I tightened the bolt to 50 ft-lb per spec, I had it like you did when tightening it, make sure to take the wheel off, push down on the rubber boot that you have on the strut, grab some pliers, I would suggest some vise grips, and grab this part from the bottom

then tighten it to spec, and you should be set. After driving for a few miles I would suggest just re torquing it just incase it loosens up a bit.

 

^ u are not supposed to touch the rod , the part you circled if thats what u mean

 

Yup never use anything to grip the rod lol. You will definitely damage it

 

Put a towel over it and grabbed it, their is no indention or anything I’m not full locking it, but to a point it is not spinning. Worked for me.

 

Per KYB -- https://www.kyb.com/knowledge-center...ghten-the-nut/

Do not use pliers or vise grips on the polished shaft. The use of pliers can cause scoring the highly polished chrome shaft. This will cause increased wear on the upper seals and in turn cause a hydraulic fluid leak from the shock or strut.

Do use a wrench (special tools are also available) to hold the shaft. There is a shouldered area near the top of the shaft, below the thread area, that is designed for use with a wrench.

 

Meh still got the job done, and you’re more to damage it with the wrench

 

Got it done with a 17mm offset wrench and a 8mm to stop the shaft from moving. Thanks guys

 

Hi All -
I am about to swap out all 4 of my struts and would like to know if it's necessary to replace the top struts mounts also.
