just got my old crx shell back from my brother.

threw in a d15b with an si trans. only thing i needed were axles. what did i do?

went to autozone and bought a set. now when i take off the car vibrates, when i let off the throttle its fine.

ive been reading old threads on h-t all night and it seems like its pretty common to get bad axles from them.

does anyone know what side axle would cause more vibration. i figured id pull one and replace it, if i have to i'll do it again on the other side.

or just take both axles back and get a refund, can u do that if they were installed?

thanks

 

i just went thru this problem tonight.....i had two sets of axles one set was in car that i pulled my zc swap out of drove into my garage no problems no vibration. So i put those axles back in and did the swap and pulled out of garage and went for ride......vibration only when accelerating. So i pulled back into garage swapped out the drivers one made no diffrence so i changed the passenger and it went away. So i was gonna start on passenger side cuz it is the longer one with out the half shaft. But i guess it is a toss up...GL

 

Yeah i had the same issue with my gsr. Most of these axles you get from auto zone and napa are aftermarket. If you put these aftermarket axles on the bench next to an OEM one you will start noticing why the aftermarket ones are so crappy. The joints tend to have all kinds of play in them where as the oem honda joints feel so solid you couldn't detect any play it them by hand. best bet is to find oem honda axles from the junkyard or someone selling them. You can always rebuild them yourself if you have to.

 

finding oem axles around here is so damn hard, ive looked all around with no luck.

my instincts are telling me to switch out the driverside axles first since its longer and would make more of a vibration, but i could be wrong...

anybody else have thoughts on this?

 

lol vatozone lol i seen some oem axels on the ef classifieds

 

If you can find Empi axle I would run those. Is the car lowered at all? If it is you may need to raise it up since the axles are binding. That's what my issue was.

 

had the same problem. It went away on it's own eventually but it was the drivers side axle.Im lowered over 3" and it wasnt binding. I got it new from NAPA.

 

Anything from autozone is usually junk. Sounds like the axles for sure.

 

When you lower a front wheel drive car and stuff the suspension as in an EF, your also stuffing the axles (making them shorter when they aren't designed to) Hence the vibrations under acceleration.

 

that is incorrect your not making them shorter in any way the only thing that happens is the joint has a higher degree between the shaft and the cv joint, as it is meant to do that. the only thing that lowering a car will do to your half shafts is it may cause your outer boots to tear, and even that is a long stretch to say. what causes vibrations are bad half shafts and negative caster . if you have a bent half shaft its going to vibrate the whole dam front end ONLY when on the throttle. lowering has nothing to do with it.

 

^ well im going to replace one axle at a time to knock out this vibration, what side do think i should start with first?

 

Your wrong about everything except the part about being lowered and the angle. It could be any one of the three major components of the axle that could cause a vibration. The outter CV, inner CV, and the shaft. Btw d-series don't have a half shaft. And negative caster won't cause a vibration. But as I was saying any part of the shaft that isn't perfectly balanced. But his problem is more complicated than just a imbalanced component. These aftermarket axles are balanced statically. Its under ACCELERATION that were getting a vibration right? That what he said specifically. So that means its balanced while under very little load and imbalanced under heavy loading conditions. Whats happening is the joint(s) are a shitty wobbly crap **** of a fit compared to the oem axles. So when you load it moves a little bit. This puts the joint(s) at a slight angle compared to its normal center and therefore it rotates not around its center of mass and you get a vibration. Trust me its the axles I have been through this three times already with 2 sets of NAPA axles, World PAC axles, Autozone axles. Unless you find a set of used oem axles your SOL

 

do u think autozone will give me a full refund if ive installed them?

i might get a set of the empi axles then.

 

They have a warranty? They are faulty so they should refund them.

 

They gotta come out, either for a replacement set from Autozone (eh...) or to put in newies... so either way, out they go... If they hassle you, ask for store credit, they have an easier time issuing that.

 

your like 80% wrong negative caster will absolutely cause a vibration as far as road isolation meaning: rock on the road=you feel it!!! i can see what your try to say but thats what the tripod bearings are for!! lets just agree to disagree






tripod bearings are to PREVENT that vibration in your "theory". btw: the degree that the shaft to outer joint you illustrated are not anywhere close to how they would actually be. didnt see know if he had a d series or not i was addressing his question about vibration.... the one thing we ARE agreeing on is that its the axles that are causing the problem. i havent found a "safe"
way of checking which axle is bent or properly balanced the way i check is get the car in the air and have someone in the car and run the car at about 25-30 mph usually you can spot it fairly easily

 

i finally got to take the car out for a good drive and its the most noticable in 2nd gear when accelerating.

when im in 5th gear just cruising its barely noticable.

it feesl like its the passenger axle so im going to start there. if i still have the vibration after that ill replace the driverside.

and if theres still a vibration after that, well, im going to just drive the damn car, its my winter beater and i dont have money for more axles, lol.

 

First off I just don't see how an alignment angle could cause a vibration. From what I understand the caster is the tilt of the hub. I just don't see how tilting the hub would cause a vibration. I don't see that at all...

Anyhow the tripod deal can sure as hell vibrate if its loose. Trust me man. I went through 3 sets of axles before i figured it out. I checked the shafts & everything else I could check. The test of any axle is simple. With the axle installed in the vehicle and everything tight reach up there and grab the axle and try to wiggle it around. At one point I had an oem axle installed on the passenger side and an aftermarket one on the drivers side and you could feel the difference. The aftermarket axle would move around all kinds. You could see the joints wobbling around. the oem axle felt SOLD AS A ****ING ROCK. I mean you couldn't feel any play AT ALL! When I put them both back to oem the car felt sooo damn smooth in comparison. You just you can't debate this man. btw the drawing is suppose to be an exaggeration.

 

yes the tripod bearings can vibrate if they are loose however it has nothing to do with lowering a car witch is the point ive been trying to make! and as far as caster its about road isolation if your caster is too far negative your struts transfer the impact to the rest of the body of the car instead of absorbing it smoothly. ive been doing alignments for quite some time and they are something i do on a daily basis. its not like flip burgers for a living (not looking down on anyone that does)... i work on cars all day every day. and tugging on the axles to see if they are loose will not tell you if they are properly balanced.... dont know why you keep arguing with me im telling you that it IS one of the axles!!!!

 

I had the same issue after I swapped to a b16. I thought it was my axels so i got new ones,and still had the vibrations during acceleration.. I finally decided to check my shocks and my passenger had gone out, I put new front shocks in and the vibrations went away.. dont know if this is your problem or not, but its worth it to check your shocks.

 

i replaced the passenger side axle this morning, vibrations are gone.

im a happy camper.
