Have had my '06 CRD Sport for 2 months now and I have noticed that over speed bumps and such the front goes over smoothly but the back is quite harsh, occasionally causing loss of traction and wierd handling if happen to be going around a corner. I do have the tow package and was just wondering if this included stiffer shocks. Has anyone found a shock with different valving that eliminates this?
My CRD also has the tow package, it does not include different shocks (actually doesn't include much of anything with the CRD).
The rear is on the stiff side. I remember reading a post that someone has smoothed the ride quality out by using differently valved shocks. I am a little skeptical of a different shock curing the stiff ride. It could keep the vehicle from pitching weight rear to forward- or side to side, but it will not help with the vehicle's rear refusing to absorb the impact of bumps. The main problem with your harsh ride in the rear is compression. Shocks don't handle the initial compression-- the coil springs do. The shock handles the aftermath of the springs compression. If the spring does not compress-- the shock does nothing.
The best way to get your ideal ride is to replace the springs in the rear with softer ones, If you do that, you will also need to upgrade the shocks in front. You will want the shocks in front upgraded to help keep the weight from shifting forward (or rearward) abruptly. The last shocks to upgrade would be the rear, which for smooth ride quality-- would include shocks with impact sensitive valving.
So:
Front: New shocks, high quality, faster valving than stock (faster rebound and compression), deep dampening ability desired (so they don't fade). I would not skimp on the front end here. If you are doing shocks on a diesel-- do it right.
Rear: New springs, that are slightly softer. If you get new shocks, consider impact sensing (blow off valve). The blow off valve will keep the shock stiff most of the time but will allow it to travel quickly when hitting a big bump. (Resulting in improved front to back body roll while having the ability to let the shock go through its travel quickly when hitting a big bump).
This vehicle has a rear axle and the rear will never be as plush as the front, but this will balance them out as best as possible for street use. The above is for street use by the way, the rear setup will not be ideal for 4x4. The lighter rear spring will also suck for towing. That is life. You can get load leveling shocks that adjust if you want to tow and want a softer spring too.
