How would you repair this cracked frame?

Captain Call said:
So you carry roughly 5400lbs of water (plus the bed and whatever else) up a mountain multiple times and wonder why shit stresses and cracks on an old truck? :lmao:

It's lasted this long, patch it properly and send it. :flipoff2:

Take the real advice in here and execute.

You are not wrong.

I need to dig through all my scrap metal and find some pieces that I can make the fish. Then I will do all the welding in my shop with no wind. I got the county on my ass regarding a retaining wall and that is why I needed all those railroad ties. I wanted to get that done hence the hack repair. I won't haul water until it's repaired better.

I think it's funny I can haul 200 gallons of water in the taco like it's nothing and yet the k3500 struggles and breaks with 650 gallons.

Hence my comment on the Tundra. My GF would drive the Tundra to work and simply grab 200 gallons and rally up the mountain no problem. Our existing lx470 is awesome, but can't haul water and has 356k miles :eek:

Fix the 3500 up nice enough to sell and then ...

If you really suck that bad at welding you can probably get by with drilling the crack and a bolted on reinforcement plate that covers far more area than a welded patch would.

Glob on 1/4” of bedliner onto the frame and you can sell that truck for $5k in the north east

That only works on dumbass desert dwellers. People from rusty areas know something bad is under there when they see paint on a frame.

You act like an Altima person you're gonna get Altima results.

shit's like 70 bucks for the 10lb one whenever I look at it
so I buy the solid 44lb one for the same 70 bucks instead

Those pictures might be too good. I'd fish plate it. Don't weld verticle lines on the frame.

I often hear don’t weld vertically on frames… how do they attach body mounts etc.?

don't worry about it, people make rules for themselves all the time
sometimes they're religion, other times they're religion

(if that makes sense, using it derisively in one and not in the other)

My understanding is that you can weld however you want, but you want to keep in mind that metal likes to crack along welds and that most of the load on a frame would put stress along those vertical welds. That's why we fish plate- now you've got horizontal, vertical, and diagonal welds all sharing the load.

This is what I did when I stretched my jeep frame. The coilovers and air bumps are behind this section of the frame and we've jumped and bashed our way through the desert for a few years now with no issues.

That’s weird a 30 year old truck struggles with less horsepower and an extra 4000lb saddled to it

sounds like you need either some patience or a truck payment

To be constructive, I’d run that flat bar as long as I could under the bottom web of the frame.

It's like everything you read on the internet, it's all "an it depends" type scenario and what happens in the real world vs online regurgitating lore. Look how many airbumps and shock mounts are welded vertically to a frame with no issues for example.

Another is example is look at how shitty factory welds are vs what people would get flamed for on here.
 
200 gallons is like 1600lbs
450 gallons is like 3600lbs + a bigger container

I don't understand how you think the trucks should behave similar, with 225% load?

Otherwise, I think 1/8" on the bottom web is a fantastic temp solution to get the truck back to work.
 
I'll keep you guys entertained this afternoon with my shitty welds. I'm offgrid which means some work to get the welder/generator/etc all setup. Might as well knock out some jobs that I've been meaning to do....

I'm gonna fix the hydraulic thumb on my backhoe and the rear traction bar bracket on my rig. My rig doesn't get used much, but the hoe does.

I'm gonna take a stab at this because I think I get his logic. Max payload for his 3500 is like 5,300#, and 650 gallons of water at 8.3 lbs/gal is right about there, maybe just a hair over.

Meanwhile the max payload for his Tacoma(if it's the long bed) is like 1,600 and 200 gallons of water is right there.

So basically he's loading them both to their factory spec'd max and comparing performance.

Only thing I don't know is what year and trim level his taco is.

2000 taco with the 3.4l 5 spd. It has the heaviest springs with AAL in the rear that OME had a few years ago. 220k miles.

The k3500 is stock minus the heavy duty front torsion bars. The problem is not necessarily the performance while hauling water it's the k3500 breaking something every fucking time I drive it. It's a 1998 with 64k miles. Last month it broke several lug studs on the rear.

the taco never breaks...

The way you talk about this "road" you are going to break any truck that you can get up it.

Just repair your pos chevy water truck and use that.

How in the fuck does it make sense to destroy every vehicle that you have by hauling water?

Example:
Problem: "I ruined my levis working on my greasy ass truck."
Solution: "I'll wear my Rock Revivals next time."
:homer:

65k arduous miserable miles at low speed vs 200k light relatively easy

Bet if either had an hour meter that Chevy has double the taco

Regardless sounds like you’re committed to it. If you wanna reliably work beat down old iron you need to give it some love before condemning it. Stuff like leaking hydroboost is par for the course

ATF leaking from the brake booster on to the exhaust manifold will start a fire. I have experience in this :homer:.

Power steering systems are probably responsible for more engine bay fires than gasoline in my estimation. :laughing:
