Alignment Needed When Changing Rear Arms Upper And Lower As Well........

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.

wheel not centered, as in steering wheel?
 
Info 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.

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 initially
 
I will go against the grain and say you should get one. Even though nothing is adjustable out back, the alignment for the front tires is references to the rear axle direction of travel. So if you replace worn out arms and bushings with new tight bushings and arms, there may be slight differences.
 
I used to think 4 wheel alinemen my on a RWD car was a waste of money, but I changed my mind to think once in a while is a good idea, especially on a new to you car. Torque box abuse or hitting a curb while doing donuts can bend things. This will require parts replacement, a frame shop to make adjustments or a torque box repair. There is no need to let your Mustang go down the road dog legging like an old pick up truck.
 
Alignment hadn't been done and rearlca changes, I needed an alignment
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.
 
You don't need an alignment. In fact you don't even need our advice. What is this thread about anyway? A recommended alignment that you don't want to get? Thread.\
