Wheel alignment DIY
............................................. :EDIT: I have been working on this for years. Technology and equipment cost keep changing. As some members have noted, I am busy, and other projects frequently have a higher priority. :EDIT: Links to other DIY alignment data DIY Wheel Alignment Video's http://www.peachparts.com/shopforum/video-forum/270887-diy-wheel-alignment-videos.html Everything Auto: DIY Wheel Alignment http://www.extremehowto.com/xh/article.asp?article_id=60130 DIY 4 Wheel Alignment http://www.elantragtclub.com/id554.html DIY Alignment With A Few Basic Tools And The Know-How Shared Here, You'll Never Again Be At The Mercy Of An Alignment Shop http://www.hotrod.com/techarticles/chassis/hrdp_0411_wheel_alignment_guide/index.html .............................................

READ: BEFORE TRYING TO USE THIS DIY This Do It Yourself ("DIY") is designed to provide you with general guidelines and theoretical information on how you may be able to adjust the alignment of a vehicle. Before undertaking any DIY project, or using any particular product in a DIY project, you must still independently evaluate the suitability of any products, materials or advice for your particular project. The guidelines and advice provided in this DIY is not a substitute for design, engineering, testing or common sense.

I AM NOT RESPONSIBLE FOR ANY DAMAGES YOU MAY SUFFER AS A RESULT OF USING THE INFORMATION AND GUIDELINES PROVIDED IN THIS DIY. Many people think that wheel alignments can only be done by professional mechanics. You can DIY wheel alignment at home, with the right tools, patience and practice. Be sure to take a break if you get frustrated. Understanding the alignment process will help you on any future diagnosis of suspension or steering problems. ************************************************ Wheel alignment may be out of adjustment if: #1A. Irregular tire wear is apparent. #2A. Vehicle is pulling to one side. #3A. Road hazard damage occurred. = Curb or pothole impact, followed by sudden vehicle handling characteristic alteration. #4A. The steering wheel is crooked while driving straight on a level road. Vibration is NOT a direct alignment issue, though irregular tire wear can cause tire balance and/or shifted belt issues, and road hazard damage = curb or pothole impact can wreck wheel rim and/or tire. Setting up for alignment, or Pre-Wheel Alignment VEHICLE INSPECTION: The inspection performed prior to checking and adjusting the wheel alignment angles is critical to the alignment procedure. Failure to detect and repair problems before you attempt to align the vehicle will result in FALSE wheel alignment angle measurements = wasting your time and energy. Check for: #A. Correct tire pressure. #B. Correct tire size. #C. Safe tire condition = no bald areas, shifted belts, age cracking; good tread depth, and no road hazard damage. #D. Wheel rim damage. #E. Structural rust = not safe to lift or support the vehicle. #F. Bad sway bar mounts + links, front and rear. #G. Bad differential mount. #H. Bad sub frame mounts. #I. Bad wheel bearings = check the wheel/tire assemblies for excessive radial run out. #J. Dragging or binding calipers. #K. Play in the lower ball joints = support the lower control arm, carefully use a pry bar between the lower knuckle joint and lower control arm, you are trying to lift the knuckle with a rocking motion to detect ball joint play. #L. Play in the upper ball joints = support the lower control arm, carefully use a pry bar between knuckle and upper control arm, you are trying to lift the upper control arm with a rocking motion to detect ball joint play. #M. Tie rod ends, for excessive play, binding, wear or damage = large channel lock pliers and a pry bar are needed to compress and manipulate each joint. #N. Suspension fasteners, broken or loose fasteners pose a clear danger. #O. Suspension component bushings = look for signs of wear and/or deterioration. #P. Ride height of the vehicle (specifications are listed in the service manual), if the ride height is not within specifications, check for excessive weight in the vehicle, one or more worn or broken coil springs, tire size, damaged trailing arms. #Q. Full fuel tank, a tank that is less than full will change the ride height of the vehicle. #R. Any items from the passenger compartment and trunk that are not factory equipment, and remove. ************************************************ The work area floor must be measured to make sure that the turntables and slip plates are level to each other; this is required because you will be using bubble gauges as measuring devices = false reading if all four wheels are not at the same level and on turntables or slip plates. A pair of laser levels will speed the work of leveling the turntables. IMPORTANT: All of the brakes must be locked otherwise the wheels will roll on the turntables/slip plates, giving incorrect measurements. A piece of wood jammed between the front seat and the brake pedal will work. |
All those "tools" come in at $4,952.00, I could have the stealer align my car three times a year for a decade for that amount of money. ;) :D
Not to mention all the free coffee and cookies I'd get out of all those visits.... :D |
Major changes
Major changes due to new equipment available at a cheap price.:)
I am getting this equipment to test cheap high quality home alignment.:D http://www.strait-line.com/irwin/consumer/straitline/jhtml/index.jhtml?source=google_ET |
Question,
What do the "sub frame" mounts exactly do on an MB and how do they relate to wheel allignment? Thanks |
Rear subframe mounts will affect the rear wheel alignment. This is where the rear subframe mounts to the body.
It is so much simplier on a VW Beetle. |
look at the picture

look at the picture, think of how angles would change with bad subframe bushings.
|
Got it. Thanks Hunter for the picture and explanation

Hello all,
I was wondering, what is normal tire wear that you can expect to see that an alignment or parts replacement would not necessarily fix. Like is it normal for an outer edge or inner edge to wear faster on these cars? Danny |

Roy, take this one over to the new fourm. Fits in perfectly.

I was refering to what is being discussed in this thread here: http://www.peachparts.com/shopforum/diesel-discussion/140073-w123-front-negative-camber.html?highlight=wear+normal What I was wondering is; Is it possible to remove all camber/wear on these vehicles or is a little wear ineviteable? Thanks Danny |
Hmmm. being able to align the car with tools from Home Depot. I like it.:rolleyes:

Still working on this DIY in my (laughter) spare time.

Doesn't sound like a good "DIY" move
I had my W123 aligned yesterday at a small alignment shop. Used a "Hunter" alignment rack which was all computerized and charged me $35.00. And that was the price posted on the wall in the customer lounge. Well worth it, and the fine alignment even allowed for a slightly better time in my standard 15 second acceleration run. Good luck if your going to DIY your alignment. I have more worthwhile projects in mind.
