I just did this mod on mine
My truck has 352,000 on the odo and the SR5 cluster had only 127,000
I didnt take pics becuase - well it could get misused.
get a nice clean work space.
spread out a white towel so if little screws drop they dont roll away.
Don't use the towels that your MIL gave your wife - use the one that you "liberated" from the motel that the dog sleeps on.
Remove the front clear cover
-- there are tabs holding the cover on.
-- use some screw drivers and un latch the tabs
Remove Speedo from the rest of the cluster
-- going from memory here
-- there are 1-2 screws holding the cluster on
-- there are 1-2 screws that are use to connect elec signals to the cluster
Flip the cluster over so that the face side is down and the speedo should drop out of the cluster.
Remove the speedo needle.
Take a NOTE of where the speedo needle is at rest (I think its on the pin)
-- use TWO table knives (not the steak kind - the butter kind)
-- place one "blade" under each side of the speedo needle
-- use both blades to evenly "wedge" the speedo needle off
now remove the two small phillips screw that hold the face to the speedo
The ODO is exposed.
If the face of the ODO is towards you - on the LEFT side
-- there is an odo cluster on an axle
-- this axle is retained in a groove
-- to keep the axle int he bottom of the groove a small tab of the groove is BENT up
-- this bend retains the ODO cluster
CAREFULLY pry back the tab so that the axle is clear to be removed
DONT bend it any more than you have to!!!
Work slowly - if you bust the tab of yer hosed
once the axle is loose - the digits can be separated and rotated
WARNING
The tabs can line up in more ways than one - its possible to jam things back so that some digits are not "lined up" evenly
Getting everything to line up is a PITA and takes PATIENCE.
I had to fiddle with this at least a dozen times so I had all the numbers lined up where I wanted them to be
Id shoot for a a slightly lower mileage and then spin it up by hand (I wanted the numbers exact to the mile)
When its all back toghter and the numbers are lined up...
Place the face plate back on to VERIFY that the numbers are straight
THEN AND ONLY THEN
bend the tab back to retain the axle
Reverse the steps to get it back together.
Push the speedo needle on GENTLY
