2008 Civic LX Rear Passenger Issue

2008 Civic LX Rear Passenger Issue
Hey everyone,
This is my first time posting in these forums, so bear with me, and I will try to resond quickly to any questions.

So here is what is going on. 2008 Honda Civic LX
When i drive, my steering wheel shakes and the back passenger side feels like it is shaking.
This usually happens when I am going over 55mph, but happens sporadically at lower speeds as well(but with less steering wheel shake).

I have had the tires rebalanced, and switched the tires to see if it was tire related, and it is not. I also tried to wiggle the tire to check if it was a bearing, and both seem to be fine, as does the suspension.

Any ideas? Im completely stumped.

At 10 years old it could be bad shocks but a shake can also come from a ply separation, broken belt within a tire, or a bent rim, which takes a sharp eye. (not so common these days) Basically, if all the steering and suspension parts are tight it can only be tires, wheels, or shocks.

Short story time: 15 years ago I had a Nissan that I bought from a friend who loved to shop the best prices on tires and such. He got such a deal on some rebranded Michelins marked "Shell" instead. They were great for like 30,000 miles then started to have issues that I didn't pick up on right away. Bottom line was one day listening to the news radio and heard about some tire recalls for broken belts. Sure enough the name "Shell" wasn't mentioned but Michelin was, which was about the same time it all clicked in my brain. I'll be dipped... I had 2 bum tires on the car, but the tread was almost gone so the warranty was not valid. Seems the off brand didn't carry the same warranty anyway, which is why they were cheap.

Back to your issue: If you suspect the tires / wheels I can walk you through some checks that can be done at home with no special tools other than a jack and stands.

Another thing that I would like to mention...It doesn't say here weather you checked the whole car over. I have seen many instances where a person says that the RR wheel has a problem. When I check the car out I find a LF CV joint bad or something like that. So; if you haven't already done it, I would check each wheel out for any problems.

Also; to help us understand better, any additional information that may seem irrelevant could actually help. Things like: Is the Check Engine Light on? Does it do this only going up a hill? Down a hill? When you use the brakes? On a turn?

If the CEL is on it could be an engine miss, torque shudder, or transmission slip. Brake rotors can cause a shake as can CV joints. A worn or broken motor mount can cause shaking. So please fill us in with any extra information that you may have.

Thanks for using the forum,

RE: 2008 Civic LX Rear Passenger Issue
Another thing that came to mind overnight is this wacky weather we've been having so I'll throw out another short story. A fellow comes into the dealer where I worked (years ago) and has a full service, which includes a balance and rotation of the tires. A few days later he came in steaming around the collar that his car shakes like crazy so my boss says to balance the tires again. The weird thing is it only happens in the morning. I get the car inside and the first thing I see is the wheels on the passenger side are packed solid with snow & ice, as if he parked against a plowed pile. On instinct I grabbed the car wash hose and rinsed them off, then took a ride, presto, no more shake. In this case the guy went home and parked in the slush where it would freeze over night. The extra weight of the ice was causing a nasty off balance issue. Since the day temps were 45 degrees it would melt away and be fine for the ride home.

I actually thought it was a tire as well, and mine was almost dead anyway so decided to just hope for the best. Tire blew a couple days ago, and we just got 2 new tires, and had the backs rotated to the front. So it is a different tire and rim, but the problem persists. With that being said, I would imagine that means its not a tire correct?

I even took it to the tire place and we checked for wheel bearing(tire didnt wiggle at all), and he re-balanced the tire just to be sure. Also hopped underneath and didn't see any loose/broken pieces of chassis, so I may have to dig further

This was the first thing I suspected! A number of times I pulled into a gas station to kick off the ice, only to find that none existed Sad

Check Engine Light is not on(only TPMS and it's been on since I bought the car. Useless sensors.)

It seems to do it more on hills in general. Also seems to happen less when I am accelerating, and more when i coast/brake.
Also, the power steering is working funnily as well, which is strange because i just took it to the dealership for power steering issue and they replaced the pump.

Also keep in mind it only gets really noticeable at 55mph+, and increasingly bad from there.

To catch you up on my January.

Had terrible rumble and noise in entire front side. Car has bumper to bumper warranty that includes suspension even though i am lowered(on factory parts only), so took it to the dealership.

First, was Power steering pump, and driver side cv axle. Paid $100 deductible.

24 hours later, same problem. Took it back, kinda pissed. This time was passenger wheel bearing. Another $100 deductible.(hey cheaper than the parts and i dont have to do the work haha).

12 hours later(-32 degrees that night). Car doesnt start. 2 blown ignition coils. Paid $100 deductible.

Few days later. Bar that holds the hood up clip broke, bar fell over positive terminal of the battery, melted the post.........$200 for new battery and new high quality terminals.

So I'm $500 into car repairs this January already. Running out of money to spend haha. If yall could help out would be amazing.

It is 100% passenger side related, and the front passenger just got new wheel bearing and both front tires are brand new, others less than 10k miles easily.

By the way, thanks in advance for anything that you help me figure out.

When it comes to cars, I can fix things on my own, but only if i know what is wrong.

Don't have enough experience/knowledge to diagnose most things, especially when it is suspension/wheel/tire related. Im basically useless.

RE: 2008 Civic LX Rear Passenger Issue
More thoughts: A good fix comes from a good diagnosis, which usually comes from experience, although sometimes that's a bad experience. (ok, enough old jokes)

A balance issue should be consistent with speed so you could duplicate it with the wheels up on jacks at the same 55 MPH. (at least for the front) Ply separations and bulging side walls / broken belts are strictly a visual so I'll throw out what I do to eliminate that. Jack up a wheel so you can spin it by hand and place an object near the side of the tire. (block of wood or spray can will do) Rotate the tire and look closely at the tread and the side wall (inside and outside) to notice if there are any variations more than 1/4". What you are observing is the gap between the stationary object and the tire. Repeat for each wheel. A bad tire might also give you a clue at say 5 mph in a parking lot because you will have a minor head bobbing sensation. (the tire is not completely round)

Checking shocks for another possible solution: Put your foot or knees on the bumper and bounce the car several times. Jump off and notice if the bouncing stops right away. If it bounces 2-3 times you have bad shocks. Also, if there's any trace of shock oil at the shaft seal, you have a bad shock, especially if they are gas shocks. IOW, the internal valving is different so if there's an oil leak the shock is totally useless... much worse than a conventional shock that just started leaking oil.

Other possible suspects would be a bad CV joint that only shows up under load with light acceleration / deceleration. Sometimes a worn motor mount can cause misalignment in the CV joints making it worse. (too much engine movement)

Last but not least, you may have an engine skip. OTOH, if it goes on for more than 5 seconds that should trigger the engine light and a fault code.

Keep digging and feeding us info and we'll eventually get this sorted out.

RE: 2008 Civic LX Rear Passenger Issue
I'm still not convinced with the, "It's 100% passenger side related," statement. Just last week I test drove a pickup for a guy. I told him I thought that it was the passenger side, front wheel bearing. But I would have to jack it up and check it to be sure. He told me that the problem was on the driver's side and he would take it somewhere else to have them check it. So when he got to the other shop they jacked it up and the passenger side wheel bearing was so bad that they said he was lucky that the wheel didn't fall off. I have seen this dozens of times. Even my own diagnosis of where I thought the problem was has been incorrect more than once. So my rule is to start where you "think" the problem is, but check everything. I would even check the wheel bearing and CV joint that were already replaced. Nothing says that they can't be bad even though they are new.

You say you aren't good at diagnosis because you lack experience. Experience will teach you that good diagnosis means you can't get something stuck in your head. If you look at the RR wheel bearing a dozen times and it was good every time...look somewhere else! There have been several times that I had a problem and my mind was stuck on one thing. Rupe would give me suggestions that seemed foolish, but they turned out to be correct. So don't get stuck in a box! It can cause loss of a lot of time and money.

Can you elaborate on, "The power steering working funnily." That is a pretty broad term. Air in the lines, slipping belts, dirty filters, or a worn rack can cause a vibration.
