Rear Axle Rubbing Coilover - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

NoFlex · 10-25-2017, 07:23 AM

So I've had this problem for some time now, my rear right axle on my s13 keeps dick slapping my coilover. It sits extremely close to it to the point where the boot is touching it and rubbing. It has been like this for about 3 years. My coilover has grooves worn in the bottom housing from this. ( will try to post a pic tonight ).

I have a j30 diff with s14 axles, this also happened on the same side when I have an open diff and s13 stock axles.

any ideas

Def post a pic, I'm having trouble understanding how this is even possible. . . unless someone put the wrong axle boot on it?

happened twice with two different axles, axle is literally right next to the rear coilover

there is no way it should be that close, either the boot is the wrong boot, or something is seriously out of shape

pics or gtfo. would subframe risers fix it?

FYI S13 and S14 axles are the same, regardless of the difference in track width between the cars.

yeah, had the same issue with both s13 and 14 axles. Looking at it further and comparing one side to the other is it possible that the traction bar that controls caster is too far out ? I am thinking if turn it all the way to the shortest setting the axle may move further away from the axle.

Looks like they're pretty chubby, for rear struts.

You might try loosening the inner clamp (on the outer boot, obviously), slide the boot out (toward the diff) as far as it will go in order to stretch it and pull the pleats closer to the axle (and thus farther from the strut), and re-clamping it.

I've figured out the issue, the traction rod was set to a very long setting, I took it off (adjustable) and sthortened it by an inch or two. Now the coilover has about an inch of a half of space between the axle.

This brings me on to my next point, what is the purpose of these traction rods? For rear caster and bump steer adjustments? I am thinking about taking off my adjustable ISR ones and just using the stock arms

they are the isis V1 arms, about 5 years old, for some reason one side was extended by a lot. Alignment is just fine though.

Is there any benefit to the aftermarket adjustable arms? I think they have some play in the heim joints so I may get some oem arms

the short answer, is that adjustable traction arms are of no use for 99.9% of 240 owners.

if you are VERY advanced at suspension setup (track dedicated vehicles, race teams, etc), then adjusting traction arm length is a useful tool

there is a lot of information here on the subject

thanks for the info!! adjustables are definitely not useful for me in that case.
