I intend rebuilding my diff during the winter, but as spares are very limited, and apart from bearings, are unobtainable.
With this in mind, does anyone know if our diffs are common to other vehicles in the BMW range. I believe a torsen LSD is fitted.
Many thanks

Eventually fitted my side braces. That's everything now, front and rear braces fitted and the lot tied together with the side braces. The car feels a lot tighter, scuttle shake and tramlining appear to have been reduced and are not noticeable. Running out of jobs to do.

The question of clunky and notchy gear change continually rears its head. This is relatively easy to cure. The standard ZF gearbox as fitted to the larger engined Z3s has an inherent design problem. The gearbox shift pins being situated on the top of the box can be starved of lubrication, this is wh...

Hi PJH. I designed and manufactured them myself. Not a difficult job all that is required is a source of heat for bending the 2"x1/2" flat bar, a lathe and a drilling machine. If out want dimensions l can provide. Cheers flight. Hi again PJ. If you pm me your email address I will get you ...

Thank for that Mike.
As the light only shows for a few seconds, and from what you say, is not detrimental, I will leave well alone for the time being. If it becomes a nuisance I will look at replacing or repairing.
Many thanks again

Hi everyone. Having just wakened my 3.0i from her winter hibernation, I was reminded of a little anomaly which I noticed last year, but forgot about. The car started immediately, and ran sweetly. However within a few seconds of starting the oil low level indicator lit up, although the oil pressure l...

The 3.0i and the M are both touring cars, and neither can be considered as a sports car, both having dodgy handling. The 3.0i has more than sufficient performance for its roll in life, who needs the M.? I would suggest any one looking for a proper sports car having power to spare and perfect handlin...

Just been looking at the Z4 forum, and couldn't see any reference to the clunking or knocking which is apparent on most Z3s. What is the difference? what has changed? are any parts common to both or is the Z4 completely different? ie gearbox differential etc.

Hi all. I also have this problem, but in my case I think there's to much backlash between crown wheel and pinion. Probably compounded by a little play in the drive shafts. when turning the prop shaft by hand it really feels excessive. I consider the drive shaft play to be normal, and would like to c...

Hi All. Since changing my G/box shift pins bushes and clutch, I have now replaced the slave cylinder hose, and that troublesome little valve, and after a fairly long test drive, I can honestly say it is one of the most rewarding things one can do to a Z3. It has transformed the car gear changes from...

Hi Pedro. If you google "How to change your transmission shift pins" there is a splendid write up with photos. It is a relatively simple job, but requires gearbox removal and a set of accurately made insertion punches. These can be purchased from BMW, but if you have access to a lathe they...

I don't think my 3.0i tramlines to any great extent ie following road contours. However it is slightly erratic on bumpy roads. My Lotus Elan had the same problem after its rebuild, and Lotus called it bump steer and could be and was be completely eliminated by shimming up the steering rack. Don't kn...

Hi all. I have just changed the 5 gearbox shift pins on my 3.0i. I was in two minds whether or not to implement this change, thinking it might not be worth while. However I couldn't have been more wrong, the difference it has made gear changing is quite dramatic, the notchiness which I was used to h...

Hi. When I got my 3.0i there was no trays fitted. However on OEM it shows a small tray immediately behind the bumper as being for this car. I found that the tray from a 2.2 is much larger and covers the steering rack and will fit a 3.0 with a little plastic trimming, and it looks quite snug under th...

Thanks for the replies Southernboy & Mike.
I am shortly changing my clutch hoping to attain a better gear change. The theory being clutch drag. I intend to fit a non self adjusting clutch, and of course a solid flywheel. My car is a 3.0i so perhaps the E36 flywheel will fit.

Hi all. Has any one any experience of adjustment for the accelerator pedal and control system. On my 3.0i the pedal control is not progressive. The pedal appears to have too much free play prior to the engine revs rising. This makes for difficult driving as the first inch of pedal travel does nothin...

Hi, interesting subject. I run three cars my 3.0i, my Lotus Elan and my MG ZTT Diesel. All of them run better on branded fuel over supermarket fuels. The reason I have been quoted, is that branded fuels contain 5% ethanol, whereas the supermarket fuels contain 7% which is why it is cheaper. I haven'...

Hi All Further to my posts regarding my under floor noise, my car has been examined by several knowledgeable people, bushes have been levered, the car has been abused by releasing the clutch suddenly whilst the brakes were on, and no noise could be heard.

Hi Everyone. Reading through clunk click groan posts. I would like to flag up my own problem.

I am in the happy position of having a four post car lift, and have...

Thanks Alec, and everyone. I am reasonably happy with my car now. Just two items for attention, firstly the clutch pick up is very high up on the pedal travel possibly worn plate? and the accelerator pedal has too much travel before the revs pick up. Together it is a bad combination for stalling. An...

Hi All. I have fitted my poly bushes to my car OK. However, when I ordered them I had the choice of "concentric, or Eccentric" bushes. I plumped for concentric. The question I have, is why are eccentric bushes an option? I understand what effect the eccentricity would have, but surely thes...

Hi Del.
Yes I am certain my car suspension is fine, its total mileage from new is only 34000 miles. All the tyres are new this year, and the car has that tight new feel about it. I can live with this shortcoming but I feel more body stiffness would help.

Hi all.. Interesting thread. My 3.0i runs well, no tramlining to speak about but the ride is uncomfortable, with 225x50x16" tyres at the recommended pressure of 33psi front and 38psi rear. I have reduced the pressures to 28psi front and 32 rear. There is some improvement, but I think the big pr...

Hi Kornknarr.
