Bumper pads rusted

[thekidd]

My drivers side rear bumper pad has finally fell (pulled) off. The bolt that held it on above the muffler rusted and boke off. I glued it for a little while, but while taking out, and putting my transmission in, I think I grabed the pad and broke the pad off. I tore the middle side of the bumper off, because the pad would be right behind the muffler and while running would melt the pad. Just asking what are some fixes for this. How to get the pad back on without buying an all new bumper? Im sure that most of the pads out there also have susted bolts beyond usage if taken off.

I'd say leave it off and take the other ones off, too. Fill in the holes, sand it down and paint. But that's just because I think it looks far better without the bumper pads =)

Join the club. Mine have failed too, just to be replaced with used ones that are no better. Best bet is to remove and fill like gacook said, or go with a fiberglass bumper. That's my plan come paint time.

Yea, used ones in good condition are hard to find. You would probably have to find a used set from the West Coast, other than that, probably new is only way. I don't want to know what they cost new, probably not under 150 each.

You can tear off the inside rubber, yank out the rusted piece of metal and replace it with a new piece. Then I guess smear some rubber back on it, lotta work though for a bumper pad.

It would be my personal reference to stick with the aluminum bumper as it retains the impact shocks.

Take care and happy holidays!

.Suggest as you said. This cheap to do & minimum time involve or fiberglass from AIR not out of reach money wise but more time involve.

Lol pretty close, new $172.08 each.For the price of one of those ugly "@&* you could probably buy a fiberglass bumper.

Cars/parts don't rust here in the desert. You can climb underneath my 89 and all the fasteners are dirty from road grime but don't have any rust. Everything comes apart like it's supposed to. I'm born/raised in Pittsburgh so I know what you're going through dealing with the rust.

Google 20th Street Auto in Phoenix, they're a Porsche bone yard, (no affiliation). They should be able to ship you a decent used set that doesn't have any rust.

Good luck with your car.

I like my bumper pads... Guess I'm the oddball

while i've never had one come completely of i have fixed them when one or two of the studs have rusted off- take off the bumper - line up the holes then drill a new hole next to the rusted off stud be careful not to go all the way through thre rubber- the original holes are oblong for adjustment - then i force in a short lag bolt with a washer - it bites into the steel thats around the bolt and also into the rubber itself - haven't had one come off with this fix

in my body shop at times we have to repair the bumpers pads . on a 911 they are called guards , on a 928 they are called buffers and on a 944 they are called impact strips but they are all made of the same material .
they can be repaired with good success .
once you have it all the way off the car wash the back side with a good cleaner that will remove all the crap off it .
after it drys take a carbide rotary burr and under cut were the new stud has to go . under cut it about 1 1/2 " around the place were the stud needs to be and cut out just a little deeper than the old stud was sitting (about a 1/8" deeper ) .
after your finished with the under cutting use isopropyl alcohol and clean the new under cut hole you just made real good . wipe it with one clean rag and wipe it dry with another clean dry rag . clean it untill the wipe off rag is not wiping off any more dirt or any other crap .
let it totaly dry .
find your self a bolt the size need to replace the old one . i tend to use cheese head bolts and a body panel washer . also find a piece of tubing to side over the bolt so you will not get any of the adhesive on the threads . you could use masking tape but a piece of rubber hose works best .
get some norton 5 minute speedgrip adhesive you can get it from auto body toolmart . you should also get the mixing tips and a gun too .
put a dab of the adhesive in the hole and set the new bolt in the hole let the adhesive set up . then get the depth of the threads you will need to have the impact strip sit flush to the bumper and set the rubber hose to that depth .
once you have it set fill the rest of the under cut hole with the adhesive . let it set for the full cure time . once it's totaly cured put a dab of anti seize on the threads and install the strip back on the bumper . you don't have to tork the hell out of the impact strip just snug .
we have done 100's this way and not one has ever failed .
the down side is the cost of the gun if your only going to use it one time you may find a jobber AKA auto body paint store in your area that will rent you one if you buy the adhesive from them .

On a side note...I do intend to take mine off sometime in the not too distant future. I live in Arizona, so there should be no rust on mine. Would gladly sell them to you if you're still searching at that time (or maybe it'll prompt me to do this sooner! lol).

I ripped out the old stud and used a ball peen hammer and screwdriver to remove all the rusted steel. Then I simply potted in two bolts of the same diameter and thread with polyester resin that I bought at Home Depot. It wasn't a perfect job. Once the resin cured and I installed the pad again, there is a gap between the bumper and the pad. I can live with it because my car is a commuter and I put 30 to 40 thousand miles a year on it.

The local hardware store here sells bumper bolts for not much money. They are essentially carriage bolts but have somewhat over-sized heads. After digging out the remnants and giving the holes a good cleaning, I set the replacements in place with JB Weld. That was a year ago and all is well.

[962porsche]

i would guess just about any adhesive would work but i like the norton . 1st it's in stock at my shop and the other is there is some flexibility to it like the studs have before they get all f@&k up and rusted .

Are you still looking for bumper pads? I'm planning on removing mine this weekend. If you still need...let me know, and I'll post pics of what they look like once I've got them off.
