Hey guys, Need your opinion here.

Replaced both drive shafts on 95 Integra gsr (aftermarket driveshafts), but
when I took it for a test drive, felt a vibration on front end when accelerating.
Also a major vibration felt when applying brakes on high speeds.

Noticed that on old shafts, they have rubber dampner in between
Outboard and inboard joints. But The aftermarket drive shafts that I installed is missing
That rubber dampner. Could this be the reason?

Will appreciate your opinion. Thanks in advance.

Rebuild your OEM shafts. I had the same problem, bought new ones which vibrated, replaced them with remanufactured units with the damper, same vibration. Bought some used OEM units and had them rebuilt, vibration gone.

So you're saying the axle shaft itself is the problem?
and im better off rebuilding the old one that I took out?

Yup. Not worth chancing on the aftermarket units again when you know the OEM units work. As long as you haven't been driving on them long after they started clicking they are rebuildable.

If they're ruined buy a used one at a junkyard.

Did u rebuild yours yourself or did you have to bring them in a shop? Do you know any shop that rebuilds driveshafts?
Also not sure if i could still return these aftermarket shafts.

Any other opinions guys?

Rebuild is a cleaning, repacking grease and replacing boots any shop should be able to do it.

Shafts should be exchangeable especially if they're causing vibration. Where'd you buy them?

Ohh, I probably can do that. I believe they sell a kit for that in auto stores?

I got it from B&J in coquitlam.

Thats not how you rebuild a shaft. Thats how you repack them. If they are worn out and clicking that wont fix them.
I'm assuming you put them in yourself? Did you seat them in all the way? Did you tighten the hub nut enough? Did you lock the hub nut?
New shafts even aftermarket ones are balanced and unless you got a bent one or a rare defective one its somethin you did not the shafts themselves. I've replaced hundreds of shafts over the decades of doing this and never had a problem with bad shafts just mistakes installing them.

Yes I did put them in myself. And I also double checked that it is seated all the way. I also tightened the axle nut to around 140 ftlbs and staked.

Let me re-word the problem after I replaced the driveshafts.

-The steering wheel is more like shaking (Shimmy) when applying brakes on highway speed.
-And also, a noticeable vibration felt on acceleration.

Some says, the shaking issue might the cause of a warped rotor and not the driveshafts?

Phil@rise · 08-20-2013, 11:52 AM

Its quite possible your wheels arent on properly. Did youseat the wheel proper before tightening down? Did you tighten the wheel in a criss cross pattern to make sure it seated evenly?

Yes sir, I did.
Still getting this steering wheel shake when I step on the brake while driving around 80km/r and up.
Im guessing this would be rotor issue now?

lowside67 · 08-21-2013, 09:55 PM

Or possibly something wheel bearing related

Yes possibly. If you over torqued your wheel studs you could have warped a rotor or it possibly may have always been warped but you didnt notice it due to the fucked shaft

FlaK · 08-22-2013, 08:58 PM

did yah get your front end aligned after you reassembled the front end? good chance your suspensions out to lunch, something that would be the most obvious on the highway, as you described.

thinking bout the same thing too,probably it wasnt noticeable before due to the fucked shaft.

Wishful_Thinker · 09-14-2013, 09:52 PM

replaced rotors and pads...Shaking and vibration on steering wheel is gone.
There is still slight vibration on acceleration, i was told it might be the aftermarket shafts?

Puck Luck · 09-14-2013, 11:45 PM

Phil is spot on about repacking/rebuilding joints. Rebuilding outer joints would figuring out what was worn. The balls, the cage that houses the balls or the joint housing itself. Would need some funky measuring tools to measure up some of that, and compare to the original specs. I wouldn't even know where to find specs on that sort of stuff. Maybe a machine shop that specializes in cv joints?
But i do have a slightly different opinion in regards to "bad shafts". I've seen quite a few new or re-manufactured aftermarket shafts, right out of the box cause vibration while accelerating. Even some high mileage eom honda shafts.
It's very difficult to try and figure out if its the left or right side. Not really an exact science. Drive with the wheels off the ground and lock one wheel at a time and try to see if one is causing a vibration. Not always easy.
Nor can i say i know if its the inner, outer joint or the shaft itself causing vibrations. (although i suspect it may be the inner joint causing it). I doubt the lack of damper on the shaft would be an issue.
So to answer your question, i think its the aftermarket shafts causing the vibration. Especially if it wasnt there before. If everything with your car was reassembled correctly, then i highly doubt its an alignment issue
