ZX 1.9 1993 TD dangerous
Hi all,
My flatmates ZX has had a 'wobble' (felt thru gearstick, and causing major sideways movement of the car) It was slight, when she got the car.. it only happened under load, esp on Turbo in 2 3 and 4th gears.
after some time, it has become very very bad. , with the wheels off the ground - there is no movement there, suspension arms are good, the car recently passed MOT with no problems in this area. It HAS to be the engine mountings. Yesterday i replaced the lower central mounting. No affect at all.
I honestly cant find out which one is now causing this problem, so I am thinking to change LH and RH mounts now. GSF catalouge lists the Engine mount LH (part no. 10129 £6) and Upper RH mount (10141 £20) , is this all i need? I am guessing one or both of these parts will need pressing in etc?
I cant remember, but how easy will it be to change either of them, I think the gearbox one will need the engine tipping down a fair bit at that side? any thoughts appreciated, also is there anything anyone can think of that would cause this shaking other then these last two mounts?
With the wheels off the ground, car in 1st gear, I can rotate a wheel back and forwards, and the engine does seem to rock about 1-2 inches very easily...

The bottom mount under the engine is the most common one to fail, many threads here on replacing it, the others rarely give trouble and should be straightforward to replace. I would examine them before parting with cash.

yes Ands.. the tyres are all brand new, tracking done etc.. the problem is very severe.. but only on acceleration.. i.e. at any sustained speed the car is fine.. I am going to spend £25 on two engine mounts and do them asap...
even the driveshafts are straight.. the cv joints are good.. it can only be the mounts.....

I dont see how such worn bushes could do a wobble - while driving slow ?
By duck egg I mean a smallish tall spot on the tyre's running surface - no bulbs on the sidewall.
The duck egg developes because of air escaped from the inner cavity is trapped between the carcase and outer thread rubber layer. Nothing to do with "cheap" or reconditioned tyres. New tyres can do this - at any time in their service life.
Try swap the front & rear tyres.

sorry.. guys I am really doing a bad job of explaining this
..
She brought the car over a year ago.
It always had a bad wobble... but back then it only occured under strong torque (i.e. under turbo conditions in 2,3,4 th gears)
i then did one of the lower arm bushes - no help.
she had new tyres, tracking, and said there was an improvement... in our language, i think the problem was still there and maybe slightly hidden...
a few months later, after not really conversing with her at all..
its worse than ever...
I said it is likely to be the middle lower engine mount. We brought one and i finally changed it on Sunday.
Thsi 'wobble' is to me a very serious one (not dangerous as such, just undrivable... the wheels are held solid the car tracks fine.. but you cannot even think about acceleration) ... its not like an out of balance wheel.. its a major side to side or up and down ? lurching of the car when you even contemplate using the throttle .... its so bad i almost find it silly to talk about .. I am about too fix it. it has to be gearbox shifting fore and aft... i just have not looked at that mounting yet....
trust me.. the car will be better than ever and much like a normal ZX in days....
I just wish i had done something earlier

I really don't think changing the mounts is going to achieve much. Yes, a worn mount can amplify vibrations, but if it's got so bad that you can't drive the car, then there's something very serious that is causing the vibration in the first place.
I've driven XUD engine'd cars with all three mounts completely shot before, with no vibrations to speak of.
I have a feeling this is going to be something like a shot inner driveshaft joint, or something else that's affected by torque output.

This is not a signature.

as per this.. the small inner joint i forgot these were here.. having a silly moment..
if one or either of these are shot.. a fair mass of metal wobbling around under car... the check, crowbar, carefully lever them where they go into diff?

Just been through similar with my Xantia. Bit of vibration when driving, lots of steering wheel tugging when braking above 50 mph - and sometimes when accelerating on lock it would vibrate violently -like the whole car was jiggling side to side. I was expecting a new driveshaft at least, but I had never been happy with the tyre on the front driver's side - and on closer inspection it had an odd thin patch on it - about 6" long, 2" wide, and 1" in from the inside edge. New front tyres fitted and the tracking reset, and all is smooth again! I would never had believed an out of balance / round (as I think this one must have been) tyre would cause so much grief!
However, back to plot - new tyres have been fitted, but I'd still be tempted to jack it up and check for out of round, or running out of true. My money is on one of the inner tri-axe joints having partially seized - not sure how you would diagnose though!
