Hello all, I have a 900 II Talladega 2.0 Turbo MJ98. Due to the defect of the Simmerring of the left gearbox output, the oil ran out of the gearbox, which caused a defect of the differential (possibly further bearing damage). Apart from the consideration to have the operation repaired/repaired or only to replace the differential, I think about using a used one. My current has a translation of i=3.82 (FM55 501 S22 71 M54390). I get cheaply to a suitable Transmission with 174tsd km, which however has the translation i=4.05. What’s the difference? My current speed reaches a final speed of almost 260 km/h. If the option to exchange the differential is the best, I would possibly resort to a barrier differential, which would make sense in the Allgäu at almost 900 altitude meters. Does anyone know a source of supply? They were once in the offer for 333 Euro – unfortunately I find this no longer in the net… I hope you can help me! need my SAAB daily!
