Am I right in saying your only running 32.5" wheels? |

Yes Richard, I am running on 32.5"
yours certainly don't look like 35's
what size are they exactly? |

Here are a few pictures of the adjustable pan hard arm, along with the 2nd steering stablizer that I added to the drag link. Also a couple quick snaps of the 35x12.5x18 tires.

Wolfgang,
ESP in 463 is differently configured than in your ML (still 163?)
however, you updated ESP controller info sound very interesting - can you post details?
what about cost involved for changing the unit? |

Brent,
what did you do for clearing the 35's? Springs? Which ones?
I like the 2nd steering stbilizer |

Harald
I would love to hear more details about how to create or obtain adjustable panhard rods
I just found out mine is 760 mm also on the 55
I wonder how much change or in other words how much does the axle move sideways per inch of additional height increase from taller springs?
I am also very interested to find out since my55 is lower stock by an inch than the 500 where is a 55 in comparison to the 500 in regards to steering arm inclination.
My steering rod is 14.5 inches from the ground on the right side(passenger side) of the vehicle and the pitman arm side is half an inch less.
Is the 500 flat or higher on the pitman arm side?
Epc shows different part numbers on pitman arms too between a 55 and a 500 so I am wondering if there is a difference on their heights on that tie rod end |

Awesome looking truck!
What kind of angle to the ground does your drag link have.
Have you done any mods there? |

Hi Harald, as I've done about 10000 miles on them they are now 34 and 15/16ths.
When I'm offroading I let them down to 20psi which makes it a bit more fun but still the ESP doesn't cut in.

Hi bwillie, do you still have a good steering lock.
I've just ordered 275/70/18 to go to Morocco with, which are about 33" because of fouling when turning on the standard merc 18's.
Looks good though.

The springs are all custom with aluminum spacers up front to level. I am still playing with springs and rates. There is no rubbing at all with the 35's. I have an old drag link that I am going bend to try and make up the angle. There is some bump steer but not bad at all. |

4x4abc - 11/6/2007 6:56 AMBut we did not put the 8.25R16 in, since we also discovered that you can modify the setting for the diffs. Would it be possible to combine the diff setting with the tire settings? We chose 235/85R16 (2475 mm ) - a 4.5% gain plus 4.111:1 diffs - an additional 6% gain all in all 10.5% - 10% was needed very cool! the G500 is noticeably more responsive, accelerates faster and shifts differently, fuel economy improved by 10% (calculated with GPS since instrument cluster is still off ). And the best thing is that ESP is no longer acting up. Now that's a major improvement. Amazing what a willing mechanic can do for you. Now, based on the fact that you can combine diff and tire settings, you could input 4.111 gears and 8.25R16 tires - that would allow you to run 35" tires without upsetting ESP. http://www.collieautoworks.comMay I ask why did you choose the 4.111 diffs? They are the longest from all. Wouldn't it be better to go for a shorter one? The 4,857? That's the setting I'm using. |

Stitch,
yes, you are right - physically it would be best to have lower (numerically higher) gears to compensate for larger tires.
However, since we did not install lower diff gears , we needed to find virtual settings for the computer to make sense of the lower wheel revolutions created by the larger tires.
Since the computer does not have a setting for 295/75R16 tires, we chose 4.111 gears plus 235/85R16 tires instead.
If you would use the 4.857 setting in the computer, the system would expect higher wheel rpm than with stock tires - that combined with larger tires would create unhappy settings for the transmission plus all the electronic helpers (ESP etc)
Happy Turkey Day!

My G has a little metal label on the axles saying I have 4.111 gears.
What is stock gears on the 500? |

So if your G55 has 4.11s than you must be under 2700rpm @ 80mph (stock tire size), do you agree with my calculations?
G500 comes with 4.36:1 differentials.

Hi Chris
Thank you for the info
I will look at the rpm and let you know.
I am running 32.8 inch tires and my interest on gears is in regards to better gas mileage as Harald claims with the transmission module changes.
I have no esp issues |

Just went for a drive,around 2700 rpm dead on 80 indicated which should be 86.4 real with my tires |

more like 89mph @ 2700rpm
If you change the transmission module setting to the 8.25R16 tires your spedo should be spot on. |
