There is a lot of sand around here. I rarely get stuck, that is because of a posi-track rear end. Recently installed Monroe load adjust shock absorbers. They are quite firm and the rear end appears to sit almost two inches higher now.
The problem is that the rear axle now shakes when the tires are spinning in sand. This never happened with the old worn out shocks.
I worry that the rear axle is either damaged or may become damaged as a result of shaking. I take my dogs on frequent walks in remote locations. So shaking in sand happens a couple times/week....for a few seconds.
The 4WD doesn't work. It was that way when I bought it.
Were they installed by a shop and perhaps did that shop look at the max sidewall pressure for the tires and fill them up? If the sand is soft you'll do a lot better with less air in your tires.
I drive our mid atlantic beaches all the time and if I don't air down my tires they will hop were as airing them down make them float smoothly over our soft sand. Another thing is to possibly lay off the gas a bit as that will help the tire dig in and try to hop, "shaking the axle".
I'd try airing down before entering the sand and see how that goes. You'll be surprised how much better it will be because in sand you want to float. Remember, spinning the tires will dig you to China and you have no working 4 wheel drive to help "pull" you out!

Good ideas but 98% of the driving is on the interstate where I seek the gas mileage that normal tires pressure helps with.
I installed the shocks, that was easy.
I have a couple 4WDs but that doesn't help too much if I get stuck 18 miles away.
I have found that speed and momentum does a great deal towards not getting stuck. If I laid off the gas, the sand could stop momentum then I am screwed.
Guess I should just use a 4WD in more remote country. They are both attached to trailers at the moment...while I decide where to park the stuff on the trailer.
Installing a set of shock absorbers should not raise or lower a car significantly. I don't understand why your rear would be 2 inches higher.
These shocks have springs on them to help with heavier loads. Exact same length as the last set.....right set. 2" is a guess...looking at visuals. Got me to thinking about a bigger set of tires to smooth out our washboard roads.
The new shocks do not like washboard roads at all. Much bumpier ride on bad roads.
First thing I'd do is verify that the shock are installed correctly. Yes, correctly. If your truck rode fine before the new shocks were installed then rode not so good. It doesn't take a rocket scientist to know the shocks are either the wrong shocks for your truck or they are installed wrong. Lastly they are defective somehow.
Probabilities are high you have a hiway tred tire on the truck and the tire has a considerable amount of wear. A good set of truck or off road tires on the rear will cure the problem. FWIW, my brother works ranches all day long. He's in charge of security and keeping the coyote and hog population under control. His ranch truck is a new Chevy Silverado extended cab 4x4 with the 5.3 engine. That POS can get stuck on asphalt. It has to be the worst 4x4 system in the world....with the factory hiway tires. He recently had a set of offroad Armstrong tires put on it by the rancher that owns the truck. No more wheel hop and it works like a 4x4 should now. Considering we are from sand country south of San Antonio, tires are the difference between going and hopping around like a frog.

You have axle hop. You have the wrong shocks. They may physically fit but they are wrong for your application.
Basically your “lift” now changed the position of your axle and allows for your tires to much more easily twist your springs from their normal arched position into a sideways S shape.
Basically your tires are gaining traction and twisting the axle housing in a downward motion. The springs try to go back to their original arch and the tires are getting traction and twisting them back. This is happening really fast. This is very bad for your drivetrain.
Take off those shocks and get some regular shocks. Shocks should never lift a vehicle
Why is your 4x4 not working? What truck do you have?
