2007 Silverado Crossmember Replacement 

Sandblasting would for sure be less work and more thorough. I spent a lot of time with the needle scaler and wire wheel on my frame. After I finish rockers and cab corners I've decided this truck has seen it's last winter. It'll still work hard as always from May thru November. Good luck on your repair.

You're welcome. Thanks for watching and leaving such a nice comment.

Thanks Zane! One of the reasons I decided to put out this video, is to show how that gas tank can lead to some very well hidden rust problems. I'm already started on the rocker-cab corner work. Time permitting, I should have the next video out sooner than later.

You're welcome. Good luck on your project.

I checked them out. It looks like they have pretty much everything to do the job right. Kinda spendy, but when you're repairing a frame you don't want to cut corners.

I didn't do the rest of the frame under the cab because this truck isn't a show truck, just an ordinary driver and I wasn't ready to try to crawl under and try to hit every nook and cranny. The frame under the cab isn't in bad shape and the truck will not see another winter on the road. I skipped the leaf springs and axle for pretty much the same reason. Those two components are unlikely to ever fail due to rust, so any work on them would be purely cosmetic. The reason I took time to descale, paint and treat the frame in the rear is because it had a lot of loose scale and was subjected to the lions share of the road salt over the years. Maybe some day it will get a full frame off restoration where the whole frame goes off for sandblasting and paint. Probably won't be by me, but by the time it moves on to the next owner, it will probably be considered a classic. Good luck on your repair.

That's life in the great white north. I don't think most people, including me, inspect their hitches very often. It's a good idea to take a look at the undercarriage now and then.

07 Chev (new body style). I got it on Amazon. The description says "rear spare tire crossmember", but it is actually the gas tank crossmember. www.amazon.com/gp/product/B08CC6Y7X7/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

You must be in the rust belt too! One thing I forgot to mention was how difficult it was to find a replacement part. They are plentiful for earlier models, but I only found one source for that crossmember for a 07-13. I'll add a link in the video comments for that part.

@TheToolmanTim . In a round about way, I'm from the rust belt. I was born and raised in Michigan till 22y/o. I've been in Florida for 23 years now. The truck I have is a gmc Sierra 2500hd duramax lb7 4x4. The cross member is from the owner before me. It was more of a mud truck then. I got it fairly cheap about 3 or 4 years ago. An been working on it ever since. The cross member is rotten from the water and mud. It's also the front one. I partially forget about it. An need to go see if the have one at the junk yard. It's so bad I'm on borrowed time and I know it. Then I'll either see the fuel tank sliding down the road or see a fire trail. Lol

I bought the crossmember from Elitewill on Amazon for $140. It looks like they dropped the price to $110 now. Other than some welding wire, rust converter and paint, that's about it.
