m8tte Posted September 20, 2006 Report Share Posted September 20, 2006 Problem on a ford puma - rapid wear ie 1000 miles inside edges of both front tyres wearing Would adjusting the tracking futher toe in aleviate this or ?................... Help! lol ps on standard suspension - but have powerflex bushes to replace the common wearing out standard rubber ones about 1 year ago same happens when i swop to and from the 17 inch wheels i also have (ps hi tony - yes it is me with the problem puma from a while back!) quote tony Hello.... If i recall we had an issue with vibration and your car... am i correct? To the problem.... If as you say you are on standard suspension, then the reason for the wear will be wheel off-set or incorrect toe... Feed me more information to how and when during the cars evolution this wear happened.... In other words what happened between everything being ok and now answer wheels and tyres were balanced on a hunter machine and sorted out - all ok tracking set to toe out 1 all angles correct print out got about 6 months ago since inside edge wearing now set to toe in 1.5 about 2 months ago but still wearing inside edge not as much in a wider area now should this be set further to toe in - how much - 3??? 4?? info These settings are for ALL models of Puma with the exception of the Ford Racing Puma additional information under a seperate link. Castor Angle = 2.5 degrees Tolerance = 3.75 to 1.25 degrees Camber Angle = 0.9 degrees Tolerance = 0.2 to -2.00 degrees Maximum Variation - left to right-hand side - Castor 1.0 degree, Camber 1.25 degrees Toe Setting Setting Adjustment = -2.0mm Toe out to +/- 1.0mm Tolerance = 0.5mm Toe in to -4.5 Toe out The 'official' Ford Line is as follows - Units are in Decimal Degrees (*): Front Wheel Alignment Caster : 1.25* to 3.75* Camber : -2.00* to 0.20* Toe: -0.76* Toe Out to 0.08* Toe In or -4.5mm Toe Out to 0.5mm Toe In Rear Wheel Alignment Camber : -2.00* to -0.50* (unless your Rear Beam is 98FB 5K952 DD, then it's: -2.80* to -1.30*) Toe: 0.13* Toe In to 0.79* Toe In or 1mm Toe In to 5mm Toe In Use at own risk lol massive variation!!!!!!!!!!!!!!! would worn shocks causeover 65,000 miles now - think bush at top of strut maybe culprit? wear more on near side tyre Quote Link to comment Share on other sites More sharing options...
Tony Posted September 21, 2006 Report Share Posted September 21, 2006 Before you invest any money on suspension and so on, you need to have the Geom measured, this expense is valid since there is an obvious problem... Unless the dampers display a visible fault then leave them for now. Quote Link to comment Share on other sites More sharing options...

Tony Posted September 22, 2006 Report Share Posted September 22, 2006 The tolerances are confusing, there is a static position, a dynamic range, and a setting range. Your only concern should be the actual static position and the setting range.. You Have, front Camber -1d 25' and -92' you should have -20', from the static -1d25 and -92' add the Dynamics then the tyres will indeed wear on the insides.

m8tte Posted October 8, 2006 Author Report Share Posted October 8, 2006 Eventually i was not not working yesterday allowing enough time to get to get to a 'proper tracking place' (i know what everyone will say me included but.................. i but did try the local fast fit place last week to check if anything major out ....... they said was set to parallel - free check lol!!! ) So .....yesterday i went to eden tyres in derby to have tracking checked and.............toe was 2.8 mm!!!! reset to -1.5 and car drives fine! full print out all angles within tollerance so sorted !
