Car Forum / Honda Cars / December 2005Alignment/tire wear problem
The front tires on my 1994 Civic EX coupe are wearing unevenly. The inside edge (2-3") of both tires has worn down almost to the belt. I'll be getting new tires and a 4-wheel alignment in a couple of days. However, I'd like to be a bit more informed about what might be causing the problem, and be prepared if the alignment guy says I need major suspension work. So, any ideas what might be causing the problem? And, if I can't get the alignment done at the place I buy the tires, should i get the alignment or the new tires first? details: tires have been properly inflated for the most part, no work done to the front end recently (save for new front brakes), no hitting of curbs or major potholes recently, first time this car is having an alignment done. > The front tires on my 1994 Civic EX coupe are wearing unevenly.

I am pretty sure only the toe of the front suspension can be adjusted on the 94 Civic (as well as most other Civics). If camber or caster (the only other two alignment settings) are off, then a suspension part is bent, worn, or damaged. You can google and find many web sites that discuss toe, camber, and caster and how their being out-of-spec may affect tire wear. For example: http://www.procarcare.com/includes/content/resourcecenter/encyclopedia/ch25/ 25readtirewear.html (notice that this site says inner tire wear indicates out-of-spec camber) Does anyone else drive the car? If so, could they have hit something? Keep checking back for input here, but I would feel very confident ordering only a front alignment. If the shop is worth its salt, it will take a few minutes and see if anything is obviously amiss with the rear suspension. Get the new tires first, then have the alignment done. For an overview of your Honda's suspension, steering, and alignment, go to www.autozone.com . On the left, click on "Repair Info," then "Vehicle Repair Guides." Click on car year, make, and model, etc. Go to the section on suspension and steering, etc. The drawings should help you to discuss this with your shop. My 1991 Civic with 172k miles has never had an alignment done. Tire wear is even. I drive pretty conservatively but sometimes on back country roads. I for one would welcome an update on what the shop finds. Good luck. > The front tires on my 1994 Civic EX coupe are wearing unevenly.

Hello, This question is for the original poster (OP). Did you buy the car new or used. I once heard a story of someone in my home town that purchased a used car that appeared to be in perfect condition. He could not keep the front wheels in alignment and had to replace the front tires about every 4 months due to the serious alignment problem. He done some research on the car and found out that the former owner had wrecked the car as as result the frame of the car was bent. After the person (that wrecked the car) had the car repaired, he realized that the frame was bent due to the alignment problem. He traded it in on another car. Somehow,the car ended up in my hometown. The person placed new tires on front of the car and traded it in on another car in a large city near our home town. He warned everyone in my hometown not to buy the car. Jason  SignatureNEWSGROUP SUBSCRIBERS MOTTO We respect those subscribers that ask for advice or provide advice.

With the advent of "un-adjustable" suspension angles that seems to be a side-effect of McPherson strut suspensions, suddenly many cars get this way and nobody knows how to fix them. I found an honest frame & alignment shop some years ago when I had a Ford truck with the twin I beam suspension that had to be bent to correct the alignment. Every used car I buy goes straight to them as soon as I get it. Since it is a frame shop, they have the equipment and expertise to do whatever needs to be done. They can replace parts, adjust whatever is adjustable, or literally bend it back into spec if necessary. Usually the bill is less than the tire shop places charge for a simple toe adjustment. I think everybody should find such a place. In answer to the other question above: If you have the alignment done while the old tires are still in place, it gives the tech a good idea what the problems are just by looking at them. If you do it this way, make sure to tell them to align it to spec and not to make any adjustments to compensate for the behavior of the worn tires. If you wait and have it done after the new tires are on, then it might take them longer to find all the problems because they won't have the clues from the old tires about what is going on in the suspension. But with the new tires in place, they can also make additional adjustments to compensate for any anomalies in the new tires. > On 11/25/05 6:03 PM, in article > jason-2511051603060001@pm1-broad-126.snlo.dialup.fix.net, "Jason" [quoted text clipped - 75 lines] > > I think everybody should find such a place. not so easy! where are you? i'd /love/ to know about a place like that! i've asked around here in the bay area many times about a small castor angle issue on my civic, and no one wants to know - they're only interested in the >$3k crash rebuild work. > In answer to the other question above: > [quoted text clipped - 9 lines] > any anomalies in the new tires. > On 11/26/05 10:13 AM, in article SbmdnYO686kLFBXeRVn-gQ@speakeasy.net, "jim beam" <nospam@example.net> wrote: >> On 11/25/05 6:03 PM, in article >> jason-2511051603060001@pm1-broad-126.snlo.dialup.fix.net, "Jason" [quoted text clipped - 8 lines] >>>> and caster and how their being out-of-spec may affect tire wear.

I'm in the Dallas, Texas area. This particular place calls itself a frame and alignment shop (specifically "Dallas Frame and Alignment"). Their specialty is frame straightening which I guess qualifies as crash repair (as opposed to rebuild). No body work, no engine work, just frame and suspension stuff. There are several such places around Dallas. I'm sure something like this must exist in other places. >> In answer to the other question above: >> [quoted text clipped - 9 lines] >> any anomalies in the new tires. >> I'm the OP of this thread. I finally had the suspension inspection done after getting some new snow tires put on. The verdict? damaged/worn/loose right lower ball joint Over a year ago, I did a tranny oil change at a Honda dealer where the technician informed me that the ball joint was a bit loose. I thought I would be selling my car within a few months so I chose to ignore it.....then I forgot about it.....then the inside of my front tires were being worn to the belt. My rear tires were wearing a bit unevenly too so it was prudent to get the 4-wheel alignment. My frame and alignment shop, I think, is one of those gems that an earlier poster discussed. It seemed quite old-school, and eminently fair and honest. I patronized them once before about 5 years ago after a mishap doing donuts in an empty snow-covered parking lot. They've been around forever (and they look it--no fancy pantsy interior or exterior), do no advertising, and always seem to be busy. However, they don't have state-of-the-art computer alignment equipment. Perhaps having skilled technicians more than compensated for this shortcoming? No matter, i have tight steering, stable handling and my car tracks dead even down unbevelled roads. I'm happy! Thanks for all the input and advice here! obligatory factoid: Toe is the most important alignment adjustment on the vehicle for preventing tire wear. An incorrect toe measurement of 1/8 inch is equal to driving a car one mile and having the tire dragged sideways eleven feet. Too much toe and the tread is soon scraped off! |
