ZX front suspension knocking/vibration
Ii've got a '94 zx with a 1.9td (not quite a 69 chevy with a 396 Bruce, but I like it). Anyway the NS suspension knocks and the car vibrates/rumbles from that area with the engine under load. I've eliminated the antiroll bar, and droplinks as causes (disconnected them for a while) and also the lower suspension arm was replaced a while ago so that should be ok. Any suggestions would be welcome.
Disconnected droplinks & ARB - and drove away in the car
That MUST have been a near 2CV experience
Anyways it seems you've got a worn out CV joint. Not unlikely on a '94 car.
PS : the ZX is a light car, should in fact be a quickie with a 1.9TD.
Me thinks you are a bit spoiled, just wait until you get a bigger car. Anything bigger than your ZX will feels sloooooow 8)

Thanks mate. It is mainly at low revs in higher gears, when engine is labouring. If you change down it disappears. The noise is quite noticeable, could it still be as you suggest? All ideas welcome, I havent dismissed the CV joint yet, just not had chance to get my scuba gear on, dive down and check it out more!
Ok guys, i'm through my MOT and looking forward to another year of happy ZX motoring. So I need to return to my noisy cv joint! Can I ignore it or does it suddenly break? Also assuming I do get it changed, can someone advise on the job ie whole shaft or just the joint, ease, time, expense etc
thank you
thank you
If the joints knackered go to the scrapyard and get another. Its probably cheaper than replacing the cv joint and far less messy. Make sure you check it doesn't click and that the threads are intact though. I got given a cross threaded one a while back and three big blokes who worked there came out to deal with me when I brought it back. We had a hell of an argument as I don't find big blokes in their place of work in broad daylight intimmidating at all, but it could have been avoided if I'd checked it in the first place.
You can check it quite easily. Get a friend to roll the car back and forward on full lock and get your ear as close to it as is safe. You can usually hear a cv joint then. Sometimes they go in a weird way you cant hear though. I had a o/s one that was knackered and all it did was make the gearstick shake around everywhere. Don't understand why but replacing the driveshaft cured it.
To totally confirm, take it off and rotate the cv joint around its extremity if it grinds and clicks or feels notchy its kaput.
I know this may sound a little patronising, please don't be patronised, are your tyres in good nick? Is the tracking and balancing right? With these being far less work I personally would check that first.
