Shaking at constant speed

[tackit]

I have a 93 ranger 3.0 and it starts shaking around 35-40. It some times feels like its bucking.
I just changed plugs & wires, and also the wheel bearings and the shocks and still no luck.

Check and make sure you don't have any bubbles in your tires, but that should be even more noticeable at low speed.

I also just had to swap my driveshaft out for a one piece after my lift. My carrier bearing bushing on the driveshaft got eaten up and it caused a similar vibration, but it got way worse after a week or so.

Make sure your tires are balanced.

Also, I've had a few vehicles that would shimmy/shake at speeds like that because of bad ball joints. This is especially noticeable if you have a little "slide" feel when you turn in one or both directions, like the truck will kind of shift one direction or the other very slightly. This could also be true for practically any rubber or similar suspension component that could be worn out and create slack in the system.

Changed out the ball joints and its still doing it and Im going to rebalance the tires tomorrow and also check the drive shaft.

I had some terrible vibration that ended up being the tires. They were worn all weird from bad springs/poor alignment. After I put my lift on I got new tires and it was immediately gone. I got the alignment fixed to keep it from happening again.

Find a local mechanic. And get that up on the lift and check everything before you kill someone.
Please

Pretty vague description, a d your solutions don't help pin point it.

Is it a vibration or a wobble
