Car is now back from the garage after big job to cut out all rust. The car looks lopsided The following are the heights from each wheel arch to the ground.
LF - 63cm, RF - 65cm, LB - 60cm, RB - 57. Questions: What should be the correct heights. What is the correct pad size and part no. What is the correct part no for replacement springs. Thank you for any advice or hepl Regards Ed Maddock. |

#1 What should be the correct height? None of the above. Its not tested that way. tire size , inflation, fender fit, measuring position etc. keep this from being an accurate measure. The idea in most MB height measurements (done with jigs) is to measure the relative compression of the suspention.
With all that said, we use your technique often to know where to look for driveability/alignment problems. We do alignments for a wide range of shops. We recently diagnosed a brand new Ford van that was being used for handicap transport. The weight of a lift situated more to the passenger side was their problem. We sent it back to the shop and they rebuilt the right rear leaf ( probably more than once) till they got the arch measurements right and we realigned it and the feedback is that the customers problem is gone (was to the dealer twice and two tire stores before it went to an independent specialist who brought it to us). This example was given to answer #2 and #3. Other than starting with new springs there are no "right" answers. The right answer is the finished project. Unfortunately your heights indicate at least two problems (unlike the van). The fact that the front is higher on the right but lower in the rear is not good. Unfortunately to really get this right (from the cars standpoint) you need the heights right with the car sitting on scales all reading the proper relative weights. The other point about your readings is that the front versus rear tell nothing with arch measurements. For basic trim I often measure the rocker moulding for levelness. The car should not be lower in the rear as they will get as they get older. ------------------ Steve Brotherton Owner 24 bay BSC Bosch Master, ASE master L1 26 years MB technician [This message has been edited by stevebfl (edited 03-19-2000).] |

Thats one way to measure it.
Another is from the jacking points on the sills to the ground.....you are measuring this from a 4 point hoist arent you? ie.hoist you drive onto? Otherwise ....that rust job might have twisted the body. Does it have hydraulic rear suspension? More info please. |

Steve/Colm,
Sorry for the delay in coming back to you - away the last week. Thanks for the replys. It's possible that they twisted the chassis when the work was been done. How can I find out if this is the case. Because of the age of the car, can I assume that the springs and shocks would be worn at this stage (177,000KM)? also the rubber pads. Should I change them and see if there is an improvement. Maybe it needs some other suspension work on the front? What are the correct spring and rubber pad Parts nos.? Thanks for all your advice and help Best Regards Ed Maddock. |

Colm,
Bad reply - I did not read your full questions. Measurements taken while on the ground No hydraulic suspension. Ed. |
