I've been on the beaches alot in the past week and from day one on the hard packed sand I have an issue.

I can drive 75mph on the hwy and it's Cadillac compfy.
I drive faster then idle speed and the front end sounds like it's going to fall out from under the Jeep.
I'm far from home and min amount of tools...
I have checked by eye/hand to see if anything had worked loose, but nothing.
My tires are all properly inflated, the Jeep steers straight and no pulling to either side, brakes are good and nothing appears to be out of the norm.

Any help would be greatly appreciated.
At this very moment I am in a small town catching wifi and some food. If you need me to take a picture(s) let me know quickly.

Doesn't really make allot of sense! How in the heck can it tell hard packed sand from say gravel, or blacktop?

Bbasso

my bad...
I should have said washboard hard packed sand.

I had an issue similar and it was my shocks were working loose... Try tightening the upper nuts in your front shocks

DFlintstone

Yea! Shocks or anything! I've been on this washboarded road for...a very long time. Washboard on a beach? We just get it on the steep spots. Sucks.

In a way it's like "feedback". The bigger rigs with dulies and I suppose larger wheels than mine power through. I go around, slow down, (way down), or shake and rattle like hell. Sometimes I drop my tire pressure to 28 (ish), lower helps more, but I got to do some highway. Don't want to flex them enough to overheat. 4WD helps some, but I don't bother. I just slow down and go around where I can. If I was just out playen, Idk, how low can you go? 20, 22Lbs?

Yea, good way to find what can rattle! My 90's hatch can hit the tale-light lens after 10 years of it. My 84 has cracks at the top corners there as well.

I checked all shock nuts/bolts and all were still tight...
I'll air down and see if that makes a difference, thanks!

DFlintstone

For me it's a BIG difference. I do 1000 mi+ highway trips. I go to 37 sometimes for that. Helps mileage and even's the wear. When I hit my road at that pressure my fillings are about rattling out! I never did google it. I suppose a supper rigid shock might help? Idk. Maybe none would be better.

We have one guy we can count on to "set up the ripples", and start the cycle on the first day after the grader smooths it out. He does not pay for his own tires or fuel. So nice for the rest of us!

Going easy on the lose and letting it pack would be thoughtful, "Deputy Dog"

I have a similar issue. Off road and I'd swear that there is something in the right front corner sounds like it's going to come apart. I had the wheel off the other day and checked everything. Sway bar link bushings were flattened so I replaced them. Today I went wheeling and about halfway through the afternoon, the noise was back. Don't know what it is, but doesn't seem to do any harm.

Upon further review, I have leaf's on my 90.

after tempting luck today, I went a little faster (w same air pressure) over the washboarded sand and the sound comes from the transmission area. I poked around and all is tight.
I don't mind going slow or airing down, I was just hoping to find/fix the cause of the sound...

DFlintstone

I've had tranny mounts go, then "radio" vibration pretty well to the body. Usually accelerating. One way to check it is to (gently), take a pry bar under there and see if it moves much, easily.

Is the exhaust pipe hitting the frame/body? That will make some noise.

Bbasso

I'll check that when I get on solid ground, thanks again!
