My 60 seems to have some bounce. When I am driving at a low rate of speed, my truck bounces alot!!! UP down Up down. Brand new tires did not correct this, they are balanced perfectly. Anybody have experiences like this any comments would help. I have aftermarket wheel on brand new 33x10.50x15. Is this the berrings, or could it be something else. Thanks
Seem to be when going slow. It is not the road , but I agree that its time for springs. There is a fairly new OME 4in lift on it, but springs are old. It seems to only occur at SLOW speeds. Then disappears. But that might just be te speed. Any thoughts. Thanks
Shocks are a likely candidate. Might do the tried and true bumper bounce test just for yucks...stand on the bumper, jump down hard a few times, so that the truck really gets some up and down movement going. Then jump to the ground. The truck should stop the up/down movement really quickly - if the shocks are good. (Shocks are also known as "dampers" because their function is to dampen movement.) If after you jump to the ground, the truck keeps moving up and down for more than 1.5 cycles, you need new shocks.
Have you ever changed your shocks on this vehicle? Spend the qualm, as driving without functional shocks can be quite dangerous if it comes down to an emergency road maneuver situation.
If you've been saving for an aftermarket lift, maybe now's the time.
PS. The bouncing indicates that your springs work, they're just not being dampened by the shocks.
Maybe this is just my retard mind. But it sounds like the springs are too stiff. Maybe remove some lower ones to allow the springs to flex and move easier. To me it seems the springs are not moving much and the tires are just taking the shock.
I'm with lowtideride here. I have a stretch of road here in Provo that is a real treat to drive on. University avenue between Provo High and downtown used to be a wild bucking ride back when I was on stock springs, shocks and seized shackles. I mean the shocks couldn't very well dampen anything, being the suspension was pogo-sticking down the road, with expansion joints in this concrete roadway spaced just so that it was like riding a kayak into choppy surf head-on. Then I went to Alcans and good shackles and rancho 9ks, still SUA. That made it bearable, but a stretch of road I avoided. Now SOA, on stock/Alcan combo, same shocks, shackles it is comparable to the ride in the 80 series, which is sorta smooth for a vehicle sprung on leaves. So to return to your issue here, I'd tear those shackles apart and rebush, grease the involved parts after a good polish with emery cloth/wire wheel and don't forget the shackle works best at a 45 degree angle with the frame. A long shackle (ie. non-stock) will tend to have a near vertical or 90 degree angle to the leaves, or the frame and that's bad, 'cause no movement means what you got. Now, somebody out there is gonna say "mine are vertical and it rides great!" imagine how good the ride could be if the shackle were free to do what it was supposed to do, which is to swing, er... free.
