I have a 99 honda civic that currently has a kink in the frame rail and I wanted to educate myself more on the terminology and understanding when it comes to bodywork. As this car has been turned away from 2 bodyshops already that don't wanna claim liablity. This was very enlightening and helpful. I'm just have to find a shop willing to section it or help in doing mor work to it.

Glad my videos could help. Thanks for watching

You mentioned the tool Rail Saver. I've watched several videos using it. You exactly described my car's bend, of course, it produced a kinky. The problem is my kink/bend start way behind not close to the front, like almost a foot. Will Rail Saver solve my problem?

[@autobodytrainingsolutions838]

I don’t know if the Rail Saver will work or not. It has to fit in the rail to the damaged area and the backside needs to be flat so it will push evenly without twisting. You would have to get the dimensions of the tool to see if it would fit. Sorry I can’t help more. Thanks for watching

@@autobodytrainingsolutions838 I spoke with one of the sellers of Rail Server. He told me that this tool will only eliminate dents but not one that is bend.

[@autobodytrainingsolutions838]

Good to know. Thanks

Hello there, many thanks for the video. I have a Nissan armada with a vertical deviation on the front of 5mm and very rear of8mm. Drivetrain and wheel alignment are perfect. Considering Nissan tolerance 3 mm do you think that rear can be fixed? Thanks in advance

[@autobodytrainingsolutions838]

Without knowing exactly how the frame is damaged, 5 and 8 mm is really not much deviation. Even though 3 mm is acceptable it’s very easy to get specs to 1mm so I would guess that you’re frame is very repairable. Hope this helps and thanks for watching

What's the best way to measure and check to see if a frame is bent and still square, no twists, etc if I don't have a shop with special tools.

[@autobodytrainingsolutions838]

I have a video coming out in August that shows how you can measure a frame at home with a few simple tools. It’s very accurate and is fairly easy to do. Thanks for watching

[@celticcraps]

@@autobodytrainingsolutions838 I happen to have a frame I'm looking at on Sunday. I thought I would measure from inside corner to inside corner to check if those were the same and then sitting level on jack stands, measure each body mount, etc to the ground .. also take a level to check as well. Would that work?

[@autobodytrainingsolutions838]

@@celticcraps that’s a start. The more places you can measure and compare, the better. The level won’t do much good because most frames don’t follow level to the earth. Until my video comes out , good luck

I am pretty sure you aren't supposed to weld back over the same spot that was spot welded from the factory. At least some or most OEMs say not to.

[@autobodytrainingsolutions838]

Thanks for your comment. The way I understand it, you shouldn’t put a resistance spot weld over an existing factory spot weld. The metal is compressed during the welding process and by putting another weld over it, the metal can’t be compressed anymore and doesn’t give an adequate weld. MiG welding over a factory spot weld shouldn’t make any difference. I hope I understand this correctly and explained it accurately. Thanks for watching

Greater than 90 degrees? I don't understand, it seems like >90 would be less severe.

[@autobodytrainingsolutions838]

If you start with a piece of metal that is perfectly straight then start bending one end up, once you get to 90 degrees that’s the limit you can go . Anymore than that it’s starts folding over on it’s self which would be in excess of 90 degrees. Hope this helps

[@balloney2175]

Maybe he meant 90 degrees inside not outside.

[@Superspeeeed]

Could I jus cut the piece out n add a new one it’s near my front suspension

[@autobodytrainingsolutions838]

It’s probably not recommended but if it’s your vehicle you can do whatever you want. Good luck and thanks for watching

[@accordfreak1]

Thanks for explaining this! Based on the video, in order to fix my frame kink i would need to cut out part of the frame to repair this. Am i right? I posted a short of what it looks like. kzbin.info6C8rpZ06jsg?si=9WAyY--7vB_aZ2Zd

[@autobodytrainingsolutions838]

From what I see it doesn’t need to be cut out. It should pull out . If possible the floor above it could be opened up to gain inside access to help get kink out . What kind of vehicle is that?

[@autobodytrainingsolutions838]

Looking at it again the top of rail seems to be enclosed but it should still be able to be pulled

[@accordfreak1]

​@autobodytrainingsolutions838 thanks! I'll try to give it a go. It's a 1963 volvo 122 passenger front frame rail. I'm assuming the previous owner hit a curb which bent the frame because the body is in good shape.

[@markmassey3506]

You can't fix it, don't listen to the alcoholic, the vehicle will never be the same.

[@efrainperezsandoval4797]

My s14 got damaged from using the jack the wrong by my cousin and I was able to fix it and have no issues with the car drive perfect
