weight of rocks

I've had 1700+ lbs in my 4 banger without a problem. In my mind, the weight is a non-issue. It's the loading that is the tricky part.

 

I think you are looking at around 1300 lb.

40 sq ft * 4 in deep = 13.3 ft^3

gravel weighs about 105 lb/ft^3, so

13.3 ft^3 * 105 lb/ft^3 = 1396.5 lb

Also, pea gravel weighs 2700 lb/ yd^3

1yd^3 = 27 ft^3

2700 lb/27 ft^3 * 13.3 ft^3 = 1330 lb

 

Would be curious to understand why they'd think that. I can't think it's just 'cause of hauling the mass around 'cause the truck's rated for towing 6500lbs.

I notice it wasn't sitting on bump stops at least!

 

towing 6500 lb is a horizontal load, with say 10-15% of it on the tongue, the seals issue would be a vertical load going onto the axle ,possibly bending it, or overloading the bearings at some point.

 

I am sure it is what Tacoyota said in this post below-but yeah I had new leafs installed a couple years ago and I swear they look tougher than the originals-they haul real good, and are stiff as hell. I love em

 

All this talk of hauling heavy weight reminds me of a story I can share with all of you. I was working for Keystone Automotive, the aftermarket crash parts company and I delivered a wheel to a customer. We refurbish wheels so when you buy one, we need a core back. Anywho, the customer that day had ordered an aluminum wheel for a tacoma and when I asked for the core back he said he would have to eat this one because the wheel had split in 2 right down the center of the drum of the wheel. I asked if he knew what happened to cause such damage and his reply, the owner of the vehicle had put to much weight in the back of the truck and because of this, the wheel failed. Ouch, that must have been one hell of a load!!

 

Thanks for the info. I am going to get it delivered. They can deliver up to 12 bob cat scoops with their dump truck for $58. I don't want to damage my truck. The stones weigh alot more than i originally though. I also though last time i hauled stones i had a 1500 91 chevy with 170,000 miles on it and put 2 scoops in it. It ran on the bump stops all the way home about 4 miles. Didnt brake anything but probably wasnt good for it.

Now that's something I can understand! I got the idea they meant the pinion seal which I couldn't understand why it would blow out from overloading.

I'm sure the trucks' GVWR considers a lot of things (not the least of which is tires, leaf springs and shocks) and the ACTUAL max weight the axle can handle safely is somewhat more than that. Would be interesting to know what that really is.
