I soon need to get the rear upper and lower control arms changed out as well as the differential well. Is is necessary to get an alignment when done?
IRS?not unless you have IRS otherwise there is not adjustments
wheel not centered, as in steering wheel?Independent Rear Suspension. And no, technically none of the rear suspension should affect the front, but don't be surprised if you find your wheel isn't centered anymore, because replacing all the rear arms may correct an axle misalignment that grew over time due to soft worn bushings.
wonder if that will mean that the front end alignment is now off if indeed the steering wheel is no loner centered?Steering wheel, yes.
coolWhen I did my springs, my wheel went from 12 o'clock to about 1130. But close to three years later, it still tracks perfectly straight and no unusual wear on the tires.
Woww. I guess I need to at least get it checked then. Probably front and rear checked at the least. I will keep an eye on things if I don't initiallyInfo for every one. The front tires in an alignment use the rear tires as a reference when adjusting toe. The thrust of the car can be changed by replacing worn out and broken bushings. If the left lower control arm bushings were shot, that would allow the axle on that side to "slide" back a fraction of a degree. The total toe of the rear axle remains the same, but the toe direction changes. This in turn will have an effect on the front tires as in they now have to be turned a little different in order to track the rear correctly.
hadn't been done when? Before the changes?I'm with @Mustang5L5 I would definitely get one if it hadn't been done. I had changes when I changed my lca's with MM products but after the alignment she tracks straight as an arrow!
Alignment hadn't been done and rearlca changes, I needed an alignmenthadn't been done when? Before the changes?
yeah i had the front alignment done after putting on new shocks and struts, bushings, ball joints, sway bar end links then new front tires. Had all that done at Geralds last yr. The last time I had a front end alignment checked/done yrs and yrs ago before last year, they looked and/or checked the rear and it was fine. So just putting tires on the rear when needed over the years, I never needed an alignment. I actually asked the guy who put my shocks and struts on about needing a rear alignment and he said I probably wouldnt even have needed a front alignment because when he does work he doesn't change anything really and get things pretty much to the T correctly . But he said I still could get it checked. When they checked the alignment I dont think they had much adjusting to do, cant remember. I think he said for the rear as well I shouldn't/wouldn't really need one.Alignment hadn't been done and rearlca changes, I needed an alignment
