Engine/Transmission (1998.5 - 2002) bouncing truck

[cmills]

I have a 99 2500 4x4 and when i pull a trailer and just haul a lawn mower, which i pull clear to the front of the trailer the truck bounces up and down almost continuously unless you are on a almost perfectly smooth road. If i pull something real heavy it doesn't do it at all. Is this because it just is bouncing on the overload springs because of so little wait?

Sounds like shocks, Bilstein or Rancho work best in my book

New shocks will fix it. The OEM shocks were junk the day they were installed, you will believe me when you get some good ones on.

not shocks

Dane, truck has new rancho RS9000's front and rear.

DC upgraded the OEM shocks in 2000, so they might be good for 10K miles My new truck now has 750 miles on it and as soon as I can get the money together I will be putting Bilsteins on it. I had them on my 2000 3500QC 4x4 and they were great.

I am assuming a riding mower

It sounds to me like the trailer isn't loaded properly. The load is to far forward, you should only have about 60% of the weight in front of the axle. I would suspect that you have much more than that with the mower all the way in the front. Try loading the mower right over the axle and see if it helps.

I realize i probably have to much weight on the front of the trailer its just easiest to load it that way because i just drive it against the bars on trailer and don't usually tie it down. I was just wondering why it was bouncing, so I assume it is just bouncing off the overloads and there is nothing wrong with the truck. Yes the mower is a rider Exmark Lazer XP ( DIESEL)

Cory,



you might want to play around with adjusting those ranchos... i have the same on mine, and it took me a while to find a nice riding setting when towing and hauling. i agree with the other suggestions too, if you read the hitch and owners manual of the truck, tounge weight should only be a small percentage of the total weight of the load. i haul a kubota that weighs around 3000 pounds on a 10k pound GVW trailer, and i always park the tractor right over the axels on the trailer. it tows and handles very nice this way with minimal bouncing when i have the shocks set on setting 2. BTW my tounge weight is just enough to lower the bed height about 3 inches when the trailer and load are attached.
