Adjusting rear control arms?

[Rt Jam]

Obviously? The only thing obvious here is you assume how many 4 link cars I have worked on. So instead of a pointless debate, put a number on this offset.

Not to the body but to the centerline of the car. Pretty sure you are just here to argue because I said NOTHING about moving the body but since you brought it up. I would hammer a quarter panel or bend a lip before shifting a rear housing over.

A rear needs to be centered and that is absolute. The debate is HOW to center it. Fix the bent chassis, fix the mount or run unequal length uppers.

Actually you did.

90% of the time, this is the body mounts, the bodies fault or poorly hung quarter panels.

No, could not find anywhere saying about moving the body. UC645, there is no fighting, this is a forum to debate, share, argue and explain.

I find adjusting upper arms to be a very interesting topic. Just sharing my views on using them to adjust pinion angle and not to center the rear housing.

The front center link is a very similar topic. I don't like to see people just randomly adjusting to center the steering wheel.

Not trying to argue just understand, how would you use the center link to center a steering wheel? I know we modify them all the time to adjust bump steer, frame clearance etc I’m just not sure how you could straighten a wheel that way

What most people do is lengthen one tie rod assembly and shorten the other. This will move the center link to 1 side which moves the steering wheel. If you are fixing bump steer, I'm sure you understand this, just not soaking in my explanation.

Basically I know why this is done and it works almost all the time. Just hate seeing when people do not fully understand this and end up with a centered steering wheel and center link off to one side because of some other reason like the steering wheel is not installed (clocked) correctly. I am from the school of center the center link, have equal length tie rod assemblies and look into why the steering wheel is not clocked correctly.

You obviously do not work on cars for a living based on your responses.

No I do not work on cars for a living. I service and repair industrial robots. You obviously like just bringing unrelated facts into a debate.

Well as someone who has worked in the automotive field for over 30 years I can tell you that your info on centering the wheel is wrong. Have you ever performed an alignment? You will find guys will find the center or high point of the steering box or rack. Then make sure the steering wheel is indexed if it can be installed in more than one position. Then the tie rods are adjusted. This of course after camber and caster are adjusted or verified to be in spec.
You can go into any shop that does alignments and that is the way it is done. I can assure you that they are not worrying if the center link is perfectly centered. The alignment is correct If the steering wheel is straight and the car goes down the road straight. But I'm sure you will have another cute response.
