Repairing a rusted unibody trailing arm mount.
Вставка
- Опубліковано 5 лис 2013
- My rear trailing arm mount was rusted out. I cut it out and welded in a patch made of heavy gauge steel plate with new high grade bolts. It may be ugly but it is extremely solid. I painted it with rust-oleum professional which has served me better than other products including eastwood chassis black and rust encapsulator. 95 Saturn SW2.
UPDATE: This repair has over 10,000 miles on it and is holding solid!
Sometimes it's a shame that unibody cars that are rusted in a few problem spots are junked instead of repaired. I've had this Saturn for over 15 years, it's a good car that has served me well so when the engine chipped a valve I decided to rebuild it and go over the body seeking out rust. These mounts, some frame patches, and rockers were easy repairs to get this car back on the road.

What I did on my 2 Saturns is that I cut and welded an extension to the trailing arms and bolted the end to the strong transverse frame the holds the back of the front seats. It is still holding (2021)
@@willboaginnsandsons3817 - Sorry, no video. It is a simple hack, really. Just bolt the extended end to any part of the "frame" that is not rusted yet. It is much less work than repairing the frame rail.
Did the exact same with mine over 40,000 miles later With the repair
Man, I wish you were local to my area. I have the same issue with my Saturn, but no one around here will touch it due to liability concerns. Here's hoping my dad or one of his friends will be able to fix it.
Chris Mapp Yeah, my guess is that most places don't want to touch structural rust repairs for two reasons. 1. Cost, most people wouldn't want to pay what the repair would cost. 2. Liability (like you said). This is a common rusting spot on these cars. I bought a car for parts awhile back and these were GONE. Someone had tried to weld some bed frame angle iron up underneath but it appears they had trouble finding anything solid to attach it to. It's scary when you start cutting into it and realize it's 10x worse than you though.
***** That's the issue with mine. There's a hole where there should be metal, unfortunately. The sad thing is that the engine and transmission are still in great shape. Of course, if someone did want to tackle it, the cost of fixing it right would probably be about the same as getting a used vehicle around here, so I might be better off cutting my losses and scrapping it.
@@DoSumpthin where are you located
Looks like a good repair to me. Yeah, the welds look a bit sad, but if that car was drivable with the rust, it will be fine. If I saw that under my car I would have scrapped it. Good job. I did cut a 65 Mustang into pieces and patched up the body with Chinese ill fitting patch panels which was a major job, but it seemed an appropriate thing to do to a 50 year old car. Now it's solid, but needs the pretty parts replaced or patched on the outside of the car. (Quarter panels, doors, fenders, hood, etc.)
What is the thickness and type of metal you are using? I have some bad unibody frame rust on my FB Mazda that needs fix'n...
I've got a '95 that needs the same thing the rest isn't to bad. going cheep
What size are the 2 bolts going into the trailing arm?? Thanks!
Where are you located i need some patching on my subaru
Gotta do what you gotta do. And for those of you who say "hater"...Well that ain't any more proper a word than "ain't" is. And I forgot where I was going with this cuz my phone beeped and my computer made some noise too...And a car went by...I think it's an attention span issue...
I wonder how long it lasted
Classic
Hi ever fixed a monte carlo frame.
I have a 2007 Chevy Equinox and it's rotted on the frame on the back that they sell the rails for the frame
Anyone think bolting through the bottom of the car if you cannot weld would work if the bottom of the car is not rusty. i have a 97 lumina slightly different connection than a saturn but same problem.
If the floor is still solid then it will hold it, but most likely if the trailing arm mount is rotted than the floor is rotted to so most people dont go that route
How thick of metal did you use
I used 2 layers 16ga steel welded together to do this same repair, welded on two M10X1.5 nuts and cut a square hole for the head of the trailing arm to clear.
dude just found out i got same problem. idk what im gonna do . its not as bad as yours was. But if its rusted out like that is it safe to drive. Because i thought it was struts or my back Springs. making that noise. And if Im driving on the highway 55mil going around a turn and hit a hole my ,,,, rear end feels like it wants to jump out underneath me. idk man. if it save to drive
Freedom Smoker that noise is the trailing arm slapping around the undersive
more chevy !!!
Mine wasn't as rusty it exactly snapped off from the the other arm
Confuscious say, " When in doubt, BOOGER WELD that shit!!"
I wish I was able to reach you I need the same repair driver side all these mechanic shops don't no how to do it
I need this done on a fbody camaro
Any ideas
Sure is difficult to weld upside down for me too. Maybe they need to invent a better welder that draws in the weld.
What about the cancer above it?
I have the exact same car with the same problem. I saved forever to get a reliable car and months later find this out. Everyone keep telling me it can’t be fixed. Now I see this. Please help me. Please.
Anything can be fixed. It's just a matter of how much time and how much currency you want to throw at it.
Doesn't have to be pretty , just has to be strong. geter done.
Yeah one guy is selling a Saturn for 700 bucks but I don’t know how to weld and I’m like passing lol 😂
I just got one for 800 with one rusted off and the other one liable to fall off. Funny shit with these “engineered to fail” points.
Yea my car is the same and no one here wants to fix it.
turn your wire speed down a little. Then you won't have such chicken shit welds there. Otherwise it works. gave your beater a few more years.
loool rust bucket i would cry if i had to do that to my car
Ya, wait till you see ur new car pmt!
That won’t last long he welded it to rust lol
Ive been a welder / fabricator for 13 years man...those welds are not good and they are not solid ...one good pot hole and that patch would rip off ...
moto9ll welding upside down is no different
moto9ll Oh please, stop exaggerating... That thing is probably still holding up
Stupid hater.
It probably still is just "fine". But not good welds.
You gotta clean the absolute shite out of it... Like with different solvents and alcohol and everything. If you get it right, the weld can fall flatter than that ugly mess. Scrubadubdub or your welds won't hold up!
Any one know what gauge steel hes useing? 1/8?
@@thespoolybois6 To me, it appears to be 1/8' thick material.
that car is a rotten death trap should be scraped then trying to patch it up my be there same car at a scrap yard that shell is better shape just switch the motor from your car into
Incorrect, as long as it was fixed properly it will be fine. It will actually me stronger than stupid spot welds
Understand the engineering of a unibody before you run your mouth.
