I've not had the time nor the money to look at this yet being crimbo, getting married in 6 months and skint.

However, something else happend this morning.

I pulled out of a junction from a stand still and turned right onto a damp(ish) road with almost zero throttle. It felt like the near side front wheel sort of tucked slightly under the car (if you know what I mean) a the rear came straight out propper drifting stylye doing probably no more than 10mph :eek:

 

Also the car seems to track badly down white lines and joins in the tarmac, seems to do it worse on the near side than the offside.

 

Anybody know what this deffo is as with money being tight I don't want to replace things that I don't actually need to.

 

Help appreciated

Paul - sorry to hear your cars got problems. For what it's worth, it sounds like you need to replace the shock/coilover and whilst doing that (it's an easyish job) check that the rubber and silicone filled tie rod bush is ok, that the 2 nuts that hold it in place on the steering? arm are tight, and not torn from their mountings. Also, check everything for tightness including all of the brake components.

 

My money's on the tie rod bushing.

 

Good luck

I have already replaced all the shocks complete with coil springs (albeit with used stock ones from a '96 model) as my NSF was shafted. What do I need to look for on the bushings if they are duff and is it these ?

You can just replace the bush can't you ?

That's the "cheapest" option

So you have replaced your shocks with ones from a 9 year old car :headvswal

 

Get new ones bud.

Paul - that's it although the bush is seen in pic 5. On Z31's you could just buy the bush but on Z32's you have to buy the whole arm - last one I bought cost £108 from Nissan. It's a complex bit of kit as its a rubber bung with a silicone filling and a star shaped piece of metal inside the silicone - it does a lot of work. If the rubber cracks then the silicone starts to leak and the bush stops holding the front wheel in place.

 

...you most likly know this - I do appologise if I'm lecturing.

 

But if you don't, once the silicone's leaking (check for cracks in the walls of the bush) then you'll get strange steering pulls (chasing the camber) and after a while, juddering when braking and under acceleration - and when it's really bad a general vibration at most speeds - quite fun.

 

You can replace these bushes by poly bushes but these give a harsher feel to the steering and they say they are too tight so rip the tie rod from the steering arm (the 2 bolts). If you do use poly bushes, removal of the existing bush is quite a task - big hammer, vice and a lot of scraping...

 

Good luck

...check the sway bar bushes too - these wear but can be removed and turned through 180 degrees to extend their life.

Cheers Jack,

 

yes I do actually get vibration at varying speed but thought that was the prop bearing :confused:

I also get strange steering pulls, both ways. Must be these.

I have seen replacement poly bushings, are these NOT reccommended ?

I think you can also get stock replacement bushings too. Will have to have a butchers (when I get time)

get a good 4 wheel alignment may help aswell,you would be surprised the differance it makes,but get the tie rods checked/changed first then a 4 wheel alignment

Prop bearing will come in about 40mph up to about 80 then smooth out. Gearbox mount will be most noticeable when cars been standing and it's like having a flatspot on a tyre at low speed - goes as the speed increases.

Re steering pull - if your tyres are 'over-square' ie wide for their height, then they'll chase the camber in the road - this puts un natural strain on the tie rod bushes and reduces their life - as does big break mods.

 

Poly bushes are a low tech solution - and I don't know of any bushes that can be used from Nissan - unless of course that you can use Z31 replacement bushes - worth checking out...

 

As for 4 wheel alignment - great idea - had mine done via a crash repair specialist (£64) after I removed lowering springs and replaced them with the 'proper' springs - drives lovely.

 

Good luck

Hmm, will think about prob bearing and gear box after I do the tie rods.

I had the 4 wheel tracking done when I replaced the HICAS unit complete with arms. Will get it re-tracked after the tie rods are done. My wheels, shocks/springs and brakes are all stock, tyres will need replacing soon though, they are scrubbing and nearly at the marker.

If you need the tie rod bushes I've got a pair with poly bushes in ready to fit as I've bought rose jointed rods, yours for £40 p&p
