Strap Wrench to hold shock shaft?
 

I have a rounded koni 9mm nut preventing me from turning the cross nut holding the shock down. Any of you ever tried a strap wrench to hold the shaft still?

Yup, though not Koni. If it's not grabbing, twist it.

I'm not familiar with the Koni design. If you want to use a strap wrench to hold the shaft from spinning my answer below applies. If you mean something else, I can't help.

I tried to hold the stock damper shafts from rotating using strap wrenches this past weekend actually. It can work but I found it to be a pretty big PITA. First of all, be careful not to scratch the damper shaft at all (my wrench handles are plastic, so I didn't have a big issue with this). Also, it can be difficult to hold up the dust covers and get the wrench through the spring coils at the same time. May not be an issue on your Koni setup, but on my stock rears I had to make a cut in the dust cover to get enough space to fit the wrench in. If using spring compressors, try to set them up in a way that you leave enough space between the spring coils for your wrench.

Also, despite my best efforts to get the strap wrench tight, I still couldn't stop the shaft from turning every time I operated my impact wrench. It would probably be best to carefully watch the shaft to see if its rotating just as you start wrenching, whether by ratchet or impact driver, to confirm its held tight. Readjust your wrench if you see the shaft slipping. I've learned my lesson and will just get pass through sockets next time.

I ran into the same issue. The instructions for the RCE T2s tell you to use a strap wrench. I'm not a great mechanic, but couldn't get it to work at all. Vorshlag published a video about this and suggested using an impact driver. That did the job for me. Search YouTube for it.

Pat: this?

asdf: Yeah, I tried that. Didn't work for me. Maybe it's just my incompetence, though.
chruchx: Yep, that's the one. Thanks.

I had a hard time holding it with just a strap wrench as well. I applied some light pressure with pliers over the rubber strap and that was enough to keep the shaft from spinning.

Instructions usually say strap wrench to prevent people from destroying their new dampers with an impact. However every shop I've been to uses an impact. You just gotta take it easy and be gentle with it otherwise you might as well just burn the money you spent on the coils. If you don't feel comfortable doing this then don't.

Not sure about Konis but is there a way to use pass through wrench in combination with another wrench to tighten the nut?

Yes, but:

Thanks for the response everyone. I'm currently trying to get in touch with the guys who made the hvt camber plates. If I can get a new concial nut from them Ill just use a angle grinder and cut the cross nut. Real Pain I tell ya
