Failing Sway Bar Bushing?
 
2 Attachment(s)
The left side looks fine but the right looks as if its leaking? The cars alignment has been acting up for a while now and with a quick inspection I'm wondering if this could be the cause. The left side looks fine but the right looks as if its leaking? Thanks - sorry if this has been posted about before.

I could be wrong, but I've never seen a bushing that had fluid in it.
Always just a solid piece of rubber/ect.

Could just be grease that got stuff on it.
It doesn't look ripped or falling apart.

Agreed, that's just a plain chunk of rubber.

Reverse down a slope (like a driveway into the street) and turn your wheel to full lock in both directions (do it twice) if you hear or feel a "pop" then your bushings are (for sure) going bad. They could still be bad without this occurring though. However no: they cannot 'leak' as they are not hollow in any way. What you're seeing is the bushing grease that is applied to the bar/bushing before install (for noise, vibration, and harshness reasons, as well as to give the bar a small amount of play). Some of the grease may have been pushed out by pressure overtime.

Those bushings are greased a little when assembled. The right side is super close to the overpipe and gets hot enough to melt the grease. It looks like a leak but meh.

I'm watching mine to see if it hardens prematurely. Can't imagine all that heat cycling is good for it but mine is still plenty supple

Thanks for all the replies everyone - seems like its nothing to worry much about.

Could the heat from the overpipe have something to do with this? Perhaps poly bushings would solve the issue.

Roll bars don't influence alignment. Bushings are installed with silicone based grease to prevent squeaks. All looks normal.

exactly the same
 
mine looks exactly the same - attribute it to the overpipe heat

My car actually does exactly what you say, and I have tried tightening everything and nothing work. Everyone said my bushing looks good and normal

Multiple people said mine looked fine, then a Porsche GT3 Cup suspension tech took one look at it and told me to new bushings. I just got the smallest diameter Perrin adjustable and I've been good for 50,000+ miles since (all my piping is ceramic coated so to be fair: my bushings no longer get as hot as average too)... if it bothers you that's not a bad price to pay, you then also end up with a better swaybar whether you fully fix the problem or not. Win win

Thanks for posting this. I had some very minor (but annoying) noise when reversing out of parking spots, especially if there was some incline. The bushings looked mostly fine. Only a small gap where the bushing is slotted.
Picture of worn bushing 75K miles

I replaced the bushings and while it's still early the noise/clunk seems to have gone away.

Also, for anyone trying to diagnose the same issue, I had noise when pulling away from a stop. Lastly, the sway bar did not have any up and down play, but I was able to move it horizontally, which the new bushings don't allow.

This would have been a very tricky diagnosis without the above info, thanks.

Edit: Actually it turned out to be the front strut mounts. Found some info on a TSB about it here.

Lots of bushings have fluid in them. Not saying these do, but lots do.

The OEM sway bar bushings are self lubricating and will ooze like that when exposed to heat from the over pipe.
