91 Civic Lower at Dr. Side Front...
.... by about two inches. Car has 175k miles on it and engine
seems in great shape and is maintained pretty carefully IMO by yours truly. The non-levelness is noticeable when standing 30 feet or so from the car. Bounce test (pushing on one side than the other of the front bumper) yields about one or two cycles. I will take off the front dr. side wheel today and inspect the suspension spring (for breakage) and damper (for leakage). I haven't heard clicking when turning, so I don't think a CV joint is necessarily broken. A few questions as I troubleshoot this, using my manual, Tegger's site covering various suspension components' replacement, and the net: -- If I replace the front dr. side spring and damper, I really should do the pass. side, too, right? -- Could someone please rattle off where I can get a new damper? (I know this is in the archives... ) My recollection is OEM is not at all critical here, right? I don't want performance. I want a damper that acts the same as when my Civic's dampers were new, at a good price. Napa? Autozone? There is a junkyard not far from whom I got a strut before. -- Other things I can check to confirm, say, a broken ball joint or other causes of the non-levelness? I see Tegger's site's comments on this but the car doesn't have any braking problems suggestive of a broken ball joint. I am using http://www.askmehelpdesk.com/advice/...hp/t-6582.html . Note that my manual indicates there is no torsion bar adjustment on my 91 Civic. |

One to two bounces sounds about right. Though it might be a little soft. On my '88 Civic, I push down on the fender and it just comes back up without any residual bouncing. > I will take off the front dr. side wheel today and inspect > the suspension spring (for breakage) and damper (for > leakage).

The bone yard might be ok for springs but I would avoid any struts there. I've found that KYB GR-2 struts work pretty well. You can get them from http://www.tirerack.com. They might be a little stiffer than stock but they drive pretty good, not too hard and not too soft. It might be a good time to do all four if you're going to do the front two. I've had a set on my '88 Civic for years now and they still work fine. The the only spec I could find in my Helm manual is for the ride height. It's 25.3 in. for the front and 25.8 in. for the rear as measured from the ground to the top of the wheel well when parked on a level surface. > -- Other things I can check to confirm, say, a broken ball > joint or other causes of the non-levelness?

Eric, thanks for sharing your experience. It helps. I checked again, and my 91 Civic is indeed much more like what you describe with your 88 Civic. Also, the difference in heights is closer to 1 to maybe 1.5 inches. > I would suspect a bad spring.

Yesterday I managed to remove and inspect thoroughly both front suspension strut (that is, damper and spring) assemblies. I also looked at the ball joints (upper and lower) and checked for play in the upper ones. I took measurements, too, at one point resting the car's weight on a jack beneath the lower control arms. I couldn't find anything near an inch off. I note that, unlike the bolts in the rear lower control arms, the bolts in the front lower control arms were a breeze to remove and looked in pretty good repair. I only sprayed a little PB Blaster on all bolts/nuts and waited ten minutes. The bushings, at least at the lower control arm, look okay, but I am not prepared to excuse them yet. I am still thinking about how the loads transmit and so what could cause the 1 inch or so drop in height. I tried switching the strut assemblies but quickly found I'd have to make more adjustments to them to get them to fit in the opposite sides. This would require a coil spring compressor, from what I can tell. I think I'm going to buy a coil spring compressor today and check on whether shims exist for the damper assembly. I am contemplating changing the lower ball joints but see the nightmare stories about separating them, at least without the best or near best tool available to do so (which admittedly might be had for $30 at Autozone) , so I am hesitating until I have more evidence that one is really, say, mashed/messed up. Tegger's photos of the car with the broken front ball joint are inspiring, to say the least. I think this is going to be a multi-month process, for budgeting reasons and to enjoy, rather than become frustrated. Lately I'm thinking that, if anything really dies on this car, it will be an important suspension component. This 91 Civic was driven in the northern U.S. for about half its life and the rear suspension bushings for sure reflects this. (But I've been over the rear suspension nightmare already, both hands on at from discussion here at the newsgroup.) |

I did some more careful measurements today, ground to top of front wheel wells. The difference in heights from driver's side to passenger's side is 11/16 inch and holding. I now think it's the bushings, possibly a bit of spring sag, and maybe a bit of wear on the ball joints. |

Tegger's photos of the car with the > broken front ball joint are inspiring, to say the least. The upper ball joint is part of the upper control arm which is about $60. The lower ball joint is pressed into the steering knuckle (I don't know the cost for replacement). You should check them for free play before you decide to go through the hassle and expense of changing them. The upper ball joint can usually be checked by squeezing it in the vertical axis with a large pair of ChanneLock pliers. If you can see the joint move up and down as you squeeze it then it should be replaced. With the lower joint, I usually check it by jacking up the car, putting it on stands, and grabbing the tire between the 4 and 5 o'clock positions. Try pulling the tire in and out and feel for free play. If you do find some, then you'll need to confirm that it's isolated to the ball joint and not the wheel bearing by having someone repeat that procedure while you watch the joint. Eric |

If the bushings are not visibly compressed (checked with the car on the ground) or cracked, then they're probably OK. I still suspect a bad spring. If you get one from the wrecking yard, you'll need to know the free length of the stock new spring and bring a tape measure with you to measure the new springs. http://www.hondaautomotiveparts.com lists 4 different part numbers for the front springs with prices varying from $48.88 ea. to $136.14 ea. I would give them a call and try to find out what the differences are between the springs as you may be able to use the less expensive units. By the way, it might be better to rent a spring compressor for a day rather than purchase it. Eric |

It did indeed look that way except I thought I could forego the brake line clamps for my brief swap (during which I would do no driving but instead just take measurements) and, if I could get the damper assembly apart, rotate certain parts to make the swap work. But since they're different part nos., I understand your point. My Chilton's manual gave checks for the ball joints similar to yours. About the springs: What's odd to me is that both under load and with the strut assembly removed, the spring lengths were the same. Uncompressed, the dr. side control arm bushing is cracked. I think the pass. side one was too. But I didn't take measurements or inspect how they appeared under load, so that seems like a good next step. I found today that Autozone will loan me a spring compressor that may fit on Honda's tiny coil springs. No charge; just a refundable deposit. Thank you. I think I'm on my way to better understanding what I might need to do at some point soon. I am trying to avoid nightmares brought on by violation of the "If it ain't broke, don't fix it" rule. Plus I am ambivalent about spending too much money on a car this old, much as I want to take it to at least 250,000 miles. |
