2nd Gen Non-Engine/Transmission Proper Alignment Specs?

Proper alignment specs

Can anyone give me or direct me to where I can get the alignment specs for a 2001. Has anybody got better specs than the dealer? My inside edges seem to wear the most.

Thanks

These are the specs that I used and they seemed to improve the ride better than the OEM specs.



Left Wheel Right Wheel

-------------- ----------------



Caster 3. 2 3. 5

Cross Caster -. 3



Camber -. 10 -. 10

Cross Camber 0. 0



Toe - standard specs, (maybe a little out if you tow a lot, they will pull in as the front end lifts up).

Try doing a search, i know i've read it here before, but just can't remember(brain cramp).

First of all let me say this: Damn all of you nice people for

wanting me to stay with aadt

Anyway, I'm not much for having a good short term memory, so bear

with me.

In a previous posting written by ???? (don't remember), they were

complaining about a shimmy in their Ram 4x4 after striking bumps in the

road.

I suggested that the front end alignment has either too little or

too much caster, thus causing a caster shimmy. He did not like my

response and changed his concern from a "shimmy" to a "bounce" (big

difference), and insisted it was the shocks. Maybe it is, I haven't

driven it. He also said the alignment "checked out". Here's the

problem:

Alignment programs (and service manuals I believe), give a wide

acceptable range for front caster on the 4x4 Rams. I believe the range

is 2 degrees to 5 degrees (if that's not correct, it's pretty close).

The problem occurs when the alignment tech (independent or dealer)

tells you that the measurements "checked out fine", just because they

were in this broad range of acceptance.

Caster readings that fall on either end of the scale are subject to

caster shimmy, even though they are "acceptable". I had to align some

30 trucks and attend a 9 hour "Dodge Ram Chassis Dynamics Diagnostics"

training session (fancy name, ehh?), before finding out that 3 degrees

to 4 degrees is the optimal caster setting for 4x4 Rams that eliminates

caster shimmy.

Below I will post what specifications I set Ram trucks to. First

I want to give a little more info on correct Ram alignments so you can

see if you had a job well done,

The eccentrics on the lower control arms ARE NOT for individual

wheel caster adjustments (even though our alignment machine says they

are). The eccentric sleeves in the upper ball joints are for adjusting

individual camber and total cross caster (difference in caster between

two front wheels). This is why replacement eccentrics are positionable

in eight different ways.

Once camber and cross caster are attained with the eccentrics, the

lower control arm eccentrics are then used to swing the caster readings

into specifications. The two eccentrics must be swung in the SAME

direction in EQUAL amounts. If they are not, it will create a setback

condition (one front wheel further forward than the other).

FYI - Comparing between the two front wheels, caster will cause a

pull to the smaller value and camber will cause a pull to the larger

value. A truck set up with caster pulling in one direction and camber

pulling in the other direction, can lead to a wandering truck; even

though it is "in specifications"!!!!!!

If the eccentrics on the lower control arms of your truck are not

pointing the same direction, the alignment was done incorrectly and the

axle was "twisted" or "forced" into position to attain the acceptable

values (seen them from the factory this way, go figure).

A correct alignment will set the truck up with a slight negative

cross caster (truck has slight pull to left) to compensate for right

hand road crown. Camber will be equal side to side slightly on the

negative side. This will help maintain acceptable camber when hauling

heavy loads, as the truck tends to lift in the front when towing.

Camber will then fall slightly positive when towing.

Just because the alignment shop says "it's in specifications", that

does not mean it is set up for proper performance and handling!!!!!!!!!



Specifications (my personal settings for every Ram I align): all specs

below are in degrees.

Thanks a lot. I knew there were some updated specs out there somewhere and just couldn't find them. I looked on Daves site don't know how I missed them. Went back just now and heck there they were. Thanks again guys.
