Off level (side to side)

[panda_man22]

Hey there, i have a 1997 k1500 with a T-bar cranked and blocks out back.

The front end sits within 1/4" from side to side
The Rear is out 1 7/8" - lower on drivers side

I assume its the left leaf, but i cant find any visual cracks or any real distinct form of deformation. The frame measurement on either side match.
I havent owened this truck long, and have recently moved some 1/2 ton loads of wood pellets and for the first time it has a full tank of gas (added weight)

Is it common for these to fatigue. and sag this much
, where is the cheapest place for an OEM 4 leaf spring

 

[DonYukon]

well these trucks will set a little off due to the massive 30 gallon gas tank it sits on the drivers side

Given its a PITA, would it make sense to rotate the spring packs every several years? Are they designated driver/passenger side? But, yeah, I can see 10+ years of a full fuel tank and a driver that hasn't in three days causing uneven fatigue...

yeah most gm trucks have the gastank lean to them and tou could crank your t bars to level out the front

so are you telling me almost a 2" sag is normal with a full tank...
seems excessive

fuel weights alot and over the years the springs will weaken

Yes. It's even got its own term. It's dubbed "Chevy Lean".

I believe its roughly 9 lbs per gallon, so a full tank at 234 lbs and the driver can definitely cause the drivers side to sag more than the passenger side. The thing is, if you replace one rear spring it will probably make it higher on the drivers side. Maybe a mild add-a-leaf is in order?

That's just a bad way around it. If his leafs are saggy and they're both worn out and at different heights, that's one thing. But making one bigger to compensate for the weight of the gas tank just means it will be higher when there isn't a lot of gas in it.

Good point.
