So I was swapping rear bumpers from Pamela to Carmen. I lifted the back carpet on Carmen and discovered the rear bumper hydraulic cover plates were crusted with rust. I then lifted Pamela's, and discovered they were nothing BUT rust!

I think I'll fab new ones out of stainless steel.

 

I seldom ever find those in good shape.

 

+1 Couldnt say why. Maybe theres some electrical isolation caused by the plastic fasteners and the painted surface, ultimately causing some sort of galvanic corrosion? Just a WAG.

 

I think it's the foam seal around the bottom perimeter. Soaks up moisture like a sponge. Trapped under that fabric sound deadening doesn't help either.

 

Don't you wish it was that easy to change your better halfs rear bumpers? "Quotes myself" "I'll take one of the Angela models as well as one of the Carmen models"




Oh and I didn't double post this time!

Heh,heh.....makes me think of that video a while back of those guys trying to get that Geo out of the snow.Pulled on a rusted out rear bumper and eventually ripped the whole back of the car off!!........."I said stop many times....Stop,Stop!!"......heh,heh.

 

well, thankfully the C channels the hydraulics rest in are pristine. it's just the cover plates in the parcel shelf that are rusted.

 

That was a great video.

My covers have holes in them.

 

you're lucky. a lot of times when removing the 14mm nuts holding the bumper shocks on, the nuts seize to the studs and the whole inner absorber turns with the nut, making it VERY difficult to remove the rear bumper. but yeah, few and far between you'll find those plates in good shape. i think you're right about the moisture being trapped in the seal.

 

I was trying to take the rear bumper off on of my parts cars and ran into the same problem, those bolts and plates are all rusted together, I couldn't get them loose. Looks like the bumper is going to the scrap yard along with the rest of the shell. Too bad.

 

well, I first tried removing the bolts the run vertically inside the bumper, securing the C on the end of the hydraulic to the metal subframe of the bumper. The two on the parts car came free easily, and one on the DD... but the last one, of course, just spun in its hole. So I took off the entire hydraulic assembly, on that side, freeing the bumper, then replaced it with one from the parts car.

OK Manntis, I'll give it one last try before sending it to the scrap yard.
