Help! Compression rod on the passenger side is shot. I read about people having replaced them 3-4 times- that is just ridiculous. Are there any aftermarket compression rods out there? I would hate to pay to have them replaced only to have to do it again in a year or two. Any help?? I don't know a ton about cars and am willing to pay $500 for parts if it's for a better unit that houses a new compression rod already in it. Thanks

 

It's not the actual rod that goes bad, it's the oem rubber bushing. You can get a replacement solid bushings (have a tendency to create some noise) or just replace the bushing itself as the part is only $30 as opposed to $300.

 

You can get these bearings and have them pressed into your current rod. A hell of a lot cheaper than an aftermarket rod.

Are the SPL solid bushings the ones that tend to make noise? I am going through the same myself, with the compression rod bushing causing some creaking and a slight clunk. I was thinking of picking up the solid to avoid replacement, or should I just replace them with OEM bushing??

 

I took a look at those bushings and immediately realized that they have no dampening effect. In other words, the rest of your suspension system will have to absorb road vibration b/c these bushings are extremely stiff-- your ride may be harsher. Asked the mechanic about these and he had the exact same thought.

I'd go with OEM, they've been modified. Also, there may be an aftermarket set that uses a polyurethane as opposed to rubber.

I'm no mechanic and know very little about this, but this was my sense.

Just my 2 cents.

 

Feedback about these bushings can be found here:

Looking at the pictures in post #84 it appears there is some sort of polyurethane or rubber disk in the middle of the bushing.

 

^^^^ You may be right! I looked at the pics from the manufacturer awhile back and didn't note that there was any type of dampening material. OP, sorry if I misled you.

My suggestion would be to get a hold of Andrei and see if there is some form of dampener on them. Hopefully I'm wrong.

Thanks for correcting me BD!

 

I'm thinking about biting the bullet and getting the SPLs. I've blown through 2 sets of bushings already, I really don't care about the NVH at this point.

All I need is a place to install them as I don't think that my press has enough gusto to get them in.

 

itgogitrev.. Did Infiniti replace the rod with the revised rod? Or did they reuse your old rod and just replaced the bushings?

 

those are fine and dandy but theyre for the 2WD ONLY! Does he make them for the G35x?? SPL pro that is...

 

I just bought the bushings myself and had a shop press them in. They lasted about 18 months before the creaking came back. We had a pretty rough winter this year and I'm certain that the combination of salt/sand on the roads did a number on them.

 

I had new rods installed by dealer 30k miles and almost two years ago....no issues yet.

 

I sprayed silicone lubricant around both ends of the power rods & the creaking
stopped completely. So far 6 months of quiet operation. Will not replace them unless
I really have to (cracked bushings...).
