Z-Monster Posted April 17, 2006 Share Posted April 17, 2006 hi guys, i have had my zx for awhile now and its almost perfect witht the exception of this vibration i managed to get rid of before in the past but now.. its just annoying the F out of me. first the specs of my car... rb25det, wheel spacers all round(new and machined to the tee), 17" rims (straight) with new tires, sylvia rack steering rack customed engine mounts along with long/prop shaft, r200 diff etc. ok so now my problem... i have had a slight vibration to my steering which effects the whole car between to 50 to 75 mph. beyond 75mph i am smooth as silk aside from the road modulations and some tyre vibration at times.... so now my question is to how should i go about this problem... i have not done on wheel balancing, but i'm affraid its a bent long shaft or a shitty engine mount. I have left my car off gear and glided at 60mph just to find out if it was my drivetrain. the vibration was still evident so i used that and concluded that the vibration has nothing to do with the drivetrain but my wheels. pls give me some suggestion to tackle this problem... thanx guys.

iaconsultants Posted April 17, 2006 Share Posted April 17, 2006 inner or outer tie rod ends could be your problem or even wheel bearings. Quote Link to comment Share on other sites More sharing options...
mentallylost Posted April 17, 2006 Share Posted April 17, 2006 Get the tires balanced. I would be willing to bet that you will find that your front wheels are out of balance. Generally if you feel the vibration in the steering wheel, it's the front. If you feel the vibration in the seat, it's the rear wheels. But that's how balancing affects the car. It's only through certain vehicle speeds that it's noticeable. Quote Link to comment Share on other sites More sharing options...
Cody 82 ZXT Posted April 17, 2006 Share Posted April 17, 2006 Usually when a vibration is just in a small range of speed it is the tire balance. Quote Link to comment Share on other sites More sharing options...
JMortensen Posted April 17, 2006 Share Posted April 17, 2006 If you have showy rims, make sure they put weights on both sides of the rim. Balancing with weights only on the inside is nicer looking, but it is a "static" balance, vs a "dynamic" with weights on both sides. Dynamic is the way to go. If you don't have a lip on the outside edge of the rim then the shop should use the stick on weights as close to the outside edge as possible.

Cody 82 ZXT Posted April 19, 2006 Share Posted April 19, 2006 Have your brake rotors checked to see if they are warped or if they have a build up of material on them that is causing proublems. Quote Link to comment Share on other sites More sharing options...
