The tires have nothing to do with alignment. The car could be aligned with the scalloped tires. They are scalloped from bad alignment, shocks, struts or damaged to the front end. An alignment in itself may not fix the problem. There may need to be some new parts installed before the alignment. You only need to replace the two scalloped tires. A four wheel alignment can be done with new ones on the front and old ones on the back. Rotating them at some point will not affect the alignment.
check and/or replace the transmission sensor
Possibly your wheels need to be aligned or your tires need to be balanced. REPLACE THE STEERING DAMPER
nothing
replace the switch
BIG JOB and you need to have the front end aligned before you drive it. TAke it to a garage.
Maybe, it depends on what had to be removed to replace the bearings. If the knuckle was removed on a fwd, it may need aligned.
To do so would be a waste of money, replace the upper ball joints first, then have it aligned.
To replace a freehub body on your bicycle, you will need to remove the cassette, axle, and bearings from the hub. Then, unscrew the lockring holding the freehub body in place and replace it with a new one. Reassemble the hub and cassette, making sure everything is properly aligned and tightened.
Remove the old tie-rod from the knuckle. Loosen (or preferably replace) adjusting sleeve. Put on new tie rod and tighten everything down. Then take it and get it aligned.
I would suggest you take this project to a shop that does alignments also. This sometimes can be alot of work and then it has to be aligned after it is installed.
Take it to someone that does it for a living. Has to be pressed in. It a real pain if you don't have a press It a pain just to get it off, Has to be aligned when put back on
This is a big job and the ft end needs aligned after it is done. Get amanual on your car from the parts store.
