How To Prepare Your Jeep For The Rubicon Trail By Nena Barlow Rock rash, mechanical failures and body damage can and do happen on this trail and any driver intent on bringing their own rig should be aware of the risks. If you think you can get through the whole Rubicon trail without a scratch of any kind anywhere, you should probably NOT go on this trip—scraping and scratches happen with even the most skilled drivers. Not only should your rig be in topform maintenance, but if your vehicle doesn’t have the following MINIMUM requirements, we will not even consider it for the trip. We have developed these minimums for the general capability and comfort for a long trip to be enjoyable by the majority of clients. Can a lesser vehicle make it through? Yes, but it will take considerably more time, with a much higher risk of damage. Even if your vehicle does have these, we may still decline to accommodate your vehicle based on other factors, like gearing ratios versus driver experience, vehicle condition concerns, or safety worthiness. VEHICLE MINIMUM REQUIREMENTS 33” or taller offroad tires (35" for wheelbase longer than 105”) Offroad means threeply sidewalls with tires in good working order—no dry cracking, sufficient aggressive tread depth and pattern, fullsize working spare. For most vehicles, this also involves having an adequate suspension lift to accommodate full articulation and turning of the larger tires. Rocker panel protection Unless you don’t mind body damage, you need some side protection, not only for the occasional slip off of a rock, but also for jacking and recovery purposes. The factory Rubicon rocker guards are barely sufficient, but they are better than some cheap aftermarket tube sliders (ask us for recommendations).

How  To  Prepare  Your  Jeep  For  The  Rubicon  Trail  By  Nena  Barlow    Rock  rash,  mechanical  failures  and  body  damage  can  and  do  happen  on  this  trail  and  any  driver  intent  on  bringing  their  own  rig  should  be  aware  of  the  risks.  If  you  think  you  can  get  through  the  whole  Rubicon  trail  without  a  scratch  of  any  kind  anywhere,  you  should  probably  NOT  go  on  this  trip—scraping  and  scratches  happen  with  even  the  most  skilled  drivers.      Not  only  should  your  rig  be  in  top-­‐form  maintenance,  but  if  your  vehicle  doesn’t  have  the  following  MINIMUM  requirements,  we  will  not  even  consider  it  for  the  trip.  We  have  developed  these  minimums  for  the  general  capability  and  comfort  for  a  long  trip  to  be  enjoyable  by  the  majority  of  clients.  Can  a  lesser  vehicle  make  it  through?  Yes,  but  it  will  take  considerably  more  time,  with  a  much  higher  risk  of  damage.  Even  if  your  vehicle  does  have  these,  we  may  still  decline  to  accommodate  your  vehicle  based  on  other  factors,  like  gearing  ratios  versus  driver  experience,  vehicle  condition  concerns,  or  safety  worthiness.          VEHICLE  MINIMUM  REQUIREMENTS    33”  or  taller  offroad  tires  (35"  for  wheelbase  longer  than  105”)  Offroad  means  three-­‐ply  sidewalls  with  tires  in  good  working  order—no  dry  cracking,  sufficient  aggressive  tread  depth  and  pattern,  full-­‐size  working  spare.  For  most  vehicles,  this  also  involves  having  an  adequate  suspension  lift  to  accommodate  full  articulation  and  turning  of  the  larger  tires.      Rocker  panel  protection  Unless  you  don’t  mind  body  damage,  you  need  some  side  protection,  not  only  for  the  occasional  slip  off  of  a  rock,  but  also  for  jacking  and  recovery  purposes.  The  factory  Rubicon  rocker  guards  are  barely  sufficient,  but  they  are  better  than  some  cheap  aftermarket  tube  sliders  (ask  us  for  recommendations).

Skid  plates  Factory  Wrangler  plates  are  okay—protection  for  your  transmission  pan,  transfer  case  and  gas  tank  are  adequate  on  factory  Wranglers,  but  we  recommend  protection  beyond  the  minimum—see  more  under  “Recommendations”  below.  Other  vehicle  makes  often  have  varying  protection  by  trim  package.      Traction  device  At  least  one  locking  axle  differential.  Both  front  and  rear  are  better.  Limited  slip,  locking  center  differential  and  traction  control  are  NOT  the  same  as  axle  lock.      Recovery  points  At  least  one  frame-­‐mounted  recovery  point  in  each  the  front  and  the  rear,  rated  for  5000  pounds  or  more.  Yes,  factory  Wrangler  hooks  are  sufficient.  No,  the  3/8”  transport  loop  is  not.        MORE  RECOMMENDATIONS    Now  that  you  have  covered  the  minimums,  here  are  a  few  more  things  we  HIGHLY  recommend  before  your  trip.  And  when  we  say  “before”  we  mean  NOW—not  just  2-­‐3  weeks  before  your  trip.  The  worst  thing  you  can  do  is  install  a  bunch  of  new  stuff  on  your  rig  the  month  before  the  trip,  and  use  the  Rubicon  trail  as  the  “shakedown”  run.      Lower  front  control  arm  skids  One  of  the  most  commonly  smashed/broken  components  of  the  Jeep  Wrangler  is  the  lower  front  control  arm  mount.    Strengthening  these  is  an  inexpensive  way  to  eliminate  a  common  stress  and  something  that  can  very  quickly  make  your  trip  unpleasant.  Parts  are  less  than  $50  and  pay  a  professional  4x4  welder  an  hour’s  time  to  install  them.      Sway  bar  motor  protection  The  push-­‐button  sway  bar  system  on  current  Jeep  Wrangler  Rubicons  is  wonderful,  but  should  be  protected  from  rock  impact  to  the  motor  and  wiring  harness.  Some  aftermarket  bumpers  have  already  incorporated  this  into  their  design,  but  if  not,  we  recommend  picking  up  a  simple  bolt-­‐on  plate  from  OR-­‐Fab:  http://www.quadratec.com/products/12025_500X_PG.htm    Steering  system  The  constant  heavy  resistance  that  your  steering  system  will  endure  on  the  trail  requires  that  you  do  two  things:  

1. Make  sure  your  entire  steering  system  is  in  top  condition  before  the  trip:  clean  fluid  (dark  fluid  means  it’s  been  cooked),  no  leaks,  tight  bolts,  and  especially  good  ball  joints  and  tie  rod  ends.

2. Practice  good  steering  habits:  no  dry  steering!  Dry  steering  is  when  you  turn  your  tires  while  the  vehicle  is  NOT  moving—this  is  very  hard  on  your  steering  components.  Try  to  always  have  the  vehicle  in  motion,  even  very  slowly,  before  turning  those  big  meaty  tires.  Sounds  simple?  It’s  harder  than  you  think…  

 Axle  Gears  You  will  find  the  constant  slow  rock  crawling  of  the  Rubicon  trail  much  more  enjoyable  with  a  vehicle  that  is  geared  properly  for  it.  The  confusing  thing  is  that  we  call  “low”  or  “deep”  gears  the  higher  number  ratio,  i.e.  4.56  gears  are  much  “lower  geared”  than  3.73  gears.  The  “lower”  gear  is  much  more  desirable  for  rock  crawling,  even  though  it  is  a  higher  number.      With  an  automatic  transmission,  one  can  compensate  for  higher  gearing  with  some  good  left-­‐foot  braking,  but  this  gets  tiring  after  all  day  (or  three  or  more  days)  of  crawling  over  rocks.  With  a  manual  JK,  you  are  going  to  work  extra  hard  without  at  least  a  65:1  crawl  ratio.  Many  people  try  to  compensate  for  shallow  gearing  by  overusing  the  clutch—believe  us,  a  burnt  up  clutch  is  the  last  thing  you  want  to  have  on  the  Rubicon  Trail.  We  recommend  a  minimum  crawl  ratio  of  55  for  automatics  and  65  for  manual  transmissions  on  JK’s.  Use  this  handy  calculator  to  find  out  your  crawl  ratio:  4Lo.com:  http://www.4lo.com/calc/gearratio.php      Regearing  is  an  expensive  and  difficult  job.  You  need  a  trusted  and  highly  recommended  professional  with  experience  specifically  in  gear  set  up.  Once  installed,  you  need  to  give  your  gears  a  good  500-­‐mile  break  in—several  short  trips  that  allow  the  vehicle  to  warm  all  the  way  up,  then  cool  all  the  way  down,  without  any  long  or  hard  highway  driving.  After  500-­‐1000  miles,  your  tech  will  want  to  check  your  fluid  for  excessive  metal,  and  may  need  to  reinspect  the  ring  and  pinion  for  the  proper  wear  pattern.  In  other  words,  this  is  also  an  upgrade  that  needs  to  be  performed  months  in  advance  of  a  big  trip.      Bumpers  While  bumpers  don’t  make  or  break  your  ability  to  run  the  Rubicon  Trail,  the  odds  of  any  factory  bumpers  surviving  the  trail  are  slim  to  none.  Also,  if  you  have  oversize  tires,  many  factory  bumpers  impede  your  full  articulation  and  steering  capability.      Winch?  Hi-­‐lift?  Recovery  equipment?    The  single  most  important  piece  of  recovery  equipment  to  bring  is  your  brain.  Please  bring  it  with  you  and  do  as  little  as  possible  to  impede  its  proper  function  while  on  the  trip.    Your  guide  will  be  prepared  with  an  impressive  arsenal  of  recovery  and  repair  equipment.  You  are  not  required  to  bring  anything  on  your  vehicle  other  than  the  things  listed  above  under  “Vehicle  Minimum  Requirements”.        

We  look  forward  to  sharing  the  trail  with  you!
