What happened to my bump stops?
'01 4x4 slt DURANGO. It seems both of my downward thrust-front bump stops have came off. Or was it even equiped with em. There seems to be a mount for em but no rubber,bolts or other evidence that they where even there. I do have a smudged lower control arm that appears to have taken a few hits at one time. If this booger should have these stops, can anyone recommend what heigth, dia., hardware,etc... that is recommended? There dosent look like a whole of travel room for much to rubber to fit in there. Thanks, T

they should be there, but i had to pull mine and replace them at 65-70k miles because theywere destroyed, only place i could get them was the stealership 
, and when putting them in make sure to put a little bit of soapy water ont he edge that gets pushed in, makes the install 10000000000 times easier (i did mine when i replaced the front shocks and noticed them completely destroyed)
here is the thread from when i had to do mine https://dodgeforum.com/forum/1st-gen...uspension.html

Here is the direct link to my fix on the issue. Pictures with/without/half destroyed, How-tos, part numbers, the entire scoop:

Sharps data above adds detail, and has the same link in the liked to page it connects to. Read it all and you will be set.

If the front end height measument isn't set then it sits too close and hits the bump stops ripping them appart. This happends if it is set to low and not at 73mm. Here is the service manual. You measure to the knucle in the middle of the Tortion Bar to the gound then to the center of the hub.
STANDARD PROCEDURE

The vehicle suspension height MUST be measured
and adjusted before performing wheel alignment procedure.
Also when front suspension components have
been replaced. This measure must be performed with
the vehicle supporting it’s own weight and taken on
both sides of the vehicle.
(1) Inspect tires.
(2) Jounce the front of the vehicle.
(3) Measure and record the distance between the
ground and the center of the lower suspension arm
rear mounting bolt head (Fig. 2).
(4) Measure and record the distance between the
ground and the center of the front wheel (Fig. 2).
(5) Subtract the first measurement from the second
measurement. The difference between the two
measurement should be 73 mm (2.9 inches) ± 3 mm
(0.12 inches).

Thanks for the input folks. I believe I know which way to go now. Diffenitely beyond the original **** poor design.
But the ride heigth issue is a little concern.
OOOOooooook! Now that I have done a 3"body lift plus a T/S lift and stuck 2k worth of Nittos and wheels under the wells, are you telling me my durango wont be able to be aligned properly per ride heigth. I have replaced all joints, upper & lower, right & left. Sway bar bushings...front and rear. And I am finishing it up with inner and outer tie rod ends for both sides...Plus the bump stops. Also the right upper control arm has been replaced after it was mangled in a wreck. So I diffintely need a good alignment. Is the heigth issue a right vs left comparison or a base line for proper alignment...In other words, if the heigth dosent meet this manufactures spec...then the alignment is for naught. I thought I have read in past posts that..."Just align the vehicle", leave the torsion bars be. Am I missing something?

You got too much invested!
The height is a mathemetical confirguration. Beween the height from the ground to the tortion bar on the A arm, then measure the height to the center of the wheel on the outer most surface. Now take the measurements and subtract them and it should equill 73mm. It's not rocket science so donl't worry. You are just over thinking it!
With this mathematical configuration it would not matter if you hav 44 inch mudders on it or low ride disks, the configuration would be the same. When the shop sets the front end to aglin it they are suppost to set the height according to OEM. People are lazy and don't do it right. It's very easy to messure it to make sure hintz the diagram I included.
Now because you have a TS lift the bump stops were probably gone before you knew it. But, because of the TS lift you have this rule would not apply. I didn't know you had a TS lift.
The reason that this is set this way is to put the right movement up and down and less torque on the ball joints for optimal ware patterns.
