Front lower contol arm bushings blown?
 
So in prepping the car for the up coming autox season I noticed the front lower control arm front bushings on both sides had black "gunk" around them. I didn't see anywhere in the surrounding area that this could have come from. Does anyone know if these bushing are fluid filled like the factory diff bushing is?

Also has anyone found any good off the shelf aftermarket replacements? The only aftermarket option I've found for the front lower arm bushing is SPL which I can't use due to the rules for my class (sphericals aren't allowed).

The bushings are liquid filled. 2 options. Replace with a new OEM arm, or install the SPL's and cheat. Don't tell anyone.

Well $hit. I guess the pre-season prep just got a lot more expensive. :crying:

I guess at least I'll have the old arms to use for making custom poly bushings. :ugh2:

The same thing happened to me. I chose to go with the SPL replacement route.

Sorry for bumping an old thread, but after researching, and without any evidence... has anyone blown their impact bushings yet (rear facing bushing on the front lower control arm)?
Or those who have upgraded to SPL impact bushing replacements and have you destroyed them during the process?

My question is; are these indeed liquid filled as well? or just the smaller front-facing bushing of the front lower control arm?

I've been researching for some impact bushings alternatives without having to run spherical bearings (SPL) for personal preference.

Posters 1 and 5 have blown the front, rear lower impact bushing. The rear lower impact bushing is silicone filled. The front, lower front bushing is not. The bushings get destroyed during the process. My thread will help you out.

I read your suspension overhaul, but it completely skipped the bushing removal as you took it to the shop. I'm well aware that they get destroyed in the processing, that's why I'm asking for those who did destroy them, witness fluid leak out.

Posters #1 and #5(if the same as #1) has the front-facing bushing blown and leaking (as seen in the provided picture) I do not see any leaking evidence of the rear-facing bushing. The picture itself proves your claim the opposite. Unless you are mixed up?

These were one of options I was looking at, but the eccentric part of the bushing throws me off. Both OEM and SPL have it centered. I can probably use it's eccentric character to skew my arms in a way I would prefer, but still in thought.

If I can remember when I'm working in the garage next I'll take a look at my old arms and see if I can find anything more conclusive than my picture in post #1.

This reminds me I still need to get a full set of those SuperPro bushings to rebuild my original set of arms.

Standard Nissan fashion. The rear bushings have 2 silicone filled chambers. Like I said. The front bushings are not silicone filled.

Other silicone filled bushings on the Z are. The rear diff bushing. The 2 front sub-frame bushings.

Appreciate that. It seems obvious on the photo you posted on the OP that the front facing bushing is fluid filled. So that is answered and shown.

The one in question is the impact bushing. I know the vertical impact design of the bushing for the rearward is new, so it might be solid?
Previously I know that nissans used horizontal bushings, such as for the compression arms.

Are you just saying they’re filled with something else and not silicone? Cause again, in the OP you can see that the front facing bushing has leaked.

Made it out to the garage and cut into one of the front bushing with a razor knife, no liquid came out. Also dug around in the knife cut with a screw driver trying to further tear the bushing. Still no fluid.

I have no idea what the black residue in the OP was but it would appear it wasn't liquid filling from the bushing.

Brendan 05-23-2019 08:06 AM

My bushings look like this too. I'm going to clean them off to see if it comes back.:confused:

Oh wow, the black residue is what was confusing me as well... So you actually replaced what you suspected as shot bushings, but it wasnt actually shot.

what about your rear bushings on the front arm? Did those leak on you?
