I recently acquired some parts from a friend who traded in his SRT-4 and no longer needed parts he had laying around. One of these parts was a Upper Boomba Motor Mount. I took it just to warn everyone on here on what can occur with the bushings within the unit. I don't know how long it was on his car. I'll probably end up removing the rest of the remainding bushings (particules), powdercoating the mount, filling them in and just keeping it in storage for an extra upper motor mount.
Me neither until now. Well about a couple/few months ago when he showed up at my house with it still on his car in that condition. Originally when it was first on his car it wasn't like that, it was intact. There was no combinations of mounts, in case it gets asked. He had the top and bottom Boomba MM's. This came off a stock turbo S1 w/basic bolt-ons.
never seen that before either. my boyfriend had those on his car for probably three years and they were perfect. great mounts actually. have you tried contacting boomba about this?
Yow. It looks like the material completely disintegrated. Were the other ones partially like that too? Do you think he got some sort of chemical on it that just ate it away? Is that even possible?
I haven't tried contacting Boomba about it. From what I've heard Boomba is hard to get a hold of. I'm not looking for a replacement mount just wanting to make other owners aware of what happened to a friend of mines Upper Boomba mount. Haven't seen this with any other Boomba mount besides this one. I don't think it was chemical related as if it were the chemical would have ate away paint and anything else within the general area this mount is at. Its really hard to say what happened. As looking at it one bushing is completely gone and the other was on its way. Only thing I can think of is the bolts or a bolt got loose and there was play within the mount to rub the poly-urethane bushings (according to Boomba) apart (into pieces). I cannot explain really what happened. All I know is I've worked on his car plenty of times and that mount was intact the times I worked on his car. Then one day he shows up at my house with the mount the way it is in the pictures.
If your a Boomba MM owner I suggest you check your bolts to make sure they are tight and have no play. This mount could just be a defective one that was not caught during production. It happens, mistakes happen. Just wanted to make everyone aware.
very strange. it does almost look like something ate it away. and that doesn't necessarily mean it would eat away at the powdercoating also. i'm not sure what type of rubber they use for the bushings, but i've never seen that happen to any rubber bushings before. would be easy to make a mold and upgrade it to use poly bushings though.
wow... that sucks... first boomba I have ever heard or seen an issue with. But I heart me my bwoody solids
the bushings are poly. it might have been chemical related, boomba mounts aren't powder coated, they are anodized, so it might not have effected the color. if the bolt was loose and allowing play and that's what caused this then it's not really a manufacturer's defect or anything, it's technically user error. i've never seen poly do that before, strange.
If it were chemical related there's plenty of other things around the mount that would get affected. Unless chemical was injected into the bushings themselves which is stupid. If chemical related... what chemical then? A acidic chemical will just eat it or burn through it or melt through it. The portion of the bushing that is still left doesn't show any signs of chemical related wear. It does show chunks broken off though like any other rubber type of material wearing/breaking off. There's no explaination as to what really happened.
Amy does have a point that they should be poly bushings... something had to not only be on there a while, but very caustic. As you stated they were laying around, where were they laying around? was it like that when he took them off?
The mount was intact on his car. About a couple/few months ago he stopped at my house with the mount on his car still except it in the condition it is in my pics. Asked me what he should do, I told him replace the mount ASAP. So he took this one off and put the stocker back on. So this occured while it was on his car.
i thought they were powdercoated. i knew they weren't painted.. didn't think about anodizing. but if it was some type of chemical, chemicals don't always affect materials the same way. not sure how they make their bushings, but the way they were made could have been the problem, or how they cured. could antifreeze that that leaked or possibly sprayed from the cap, from not being tight enough, cause the deterioration?
sounds like that 1% slip on quality control to me, cause that should NOT happen, unless he is pooring gas directly on it for 4 months straight and driving without a hood...
You are right, chemicals don't aways affect materials the same way. But for a chemical to eat a supposed poly-urethane bushing(s), I would say it would eat as well the vehicles paint within the engine bay. As most chemicals would that have just a stronge affect as such. Also you have to think of it as this. I'm looking at the mount right now. Whats left of the one bushing there's no signs of cracks. There's just chewed up looking chucks missing. It could thus be how the bushing was made. Could be a weak one, could of been many aspects between curring and so fourth as you stated. As far as the anti-freeze. I've work on his car plenty of times and never noticed a leak nor did he. If we put that into perspective though... the seal on the cap is rubber, the seal around the thermostat is rubber. Both being weaker material then poly-urethane. Now when rubber seals get worn, they usually dry rot (turn hard) because of heat, causing them to also crack, which then will cause a leak.
i'm just kinda grasping at figuring out what went wrong, as i've not seen that happen on a mount before. it's quite possible it's just a bad bushing, there are always bad batches, it happens. i would really try to contact boomba and see what they say. they are on the red board, try there. just send a pm. i have emailed them in the past and they always got back to me pretty quick, so maybe try emailing too.
