When driveshafts are worn out (cups and/or tripods) you get that specific vibrations from the front of the car, no mather what gear, ONLY during acceleration.
It seems like whole car is shaking at the front
Just drove friend t-jet, 205 000km on the clock, it has that specific shaking when accelerating, he tought that something is wrong with engine (sparks, ign. coils, injectors)

That makes sense. On my car, the vibration occurs around 60mph+ AND when the car is accelerating/maintaining a constant speed on an incline (torque applied against resistance from wheels). When the car is decelerating, the vibration does not occur.

Yes, thats it.

If you put just new grease, you will reduce vibration 20-30%. When you replace tripod and grease, vibration will be gone, because i think that cups cannot be so much damaged on low mileage, only if cups are dry, without grease at all.

Small dents inside cups (hardly felt under finger when you cross inside cup) doesnt mean that you have to change whole shaft or cups.

Tripods are not so expencive, here is Fiat OEM tripod cca 80 euros, replacement part is 40 euro, and even (funny) 10 euro for tripod made by manufacturer Pascal.

I refurbished cups on my Bravo because i wasnt informed well about shaft problems on Bravo, new grease (heavy duty for higher temperatures) and tripods would resolve problem

That is my opinion, i do all mechanical works on my Bravo by myself, not so much to spare some money that ill spend in workshop, because i love to do it.

By any chance do you have a part code for the Pascal tripod ?

What grease did you use?

Pascal G4F001PC

I checked, it was paid 9 euro with some discount. Yes, it is made of iron :funny

I used grease from our local producer INA LIS MOS EP2, 6 euro for 400gr
But i think, this is maybe better:

Lm2 high temp grease is probably better... used on brake calliper pins etc... its brilliant... dont use molly grease.

I was reading.. that MOS2 - moly grease is not suitable for the kind of forces in a tripod assembly... (although it is the best for the other end , closer to the wheel)
Some people recommend this one: Red Line 80401 CV-2 Synthetic Grease - 14 oz. Jar by Red Line Oil: Amazon.co.uk: Car & Motorbike.

i wish i could get it here.

Latest update:

Garage have confirmed that the spider bearings are shot and the grease in the joint has dried up. The cup is absolutely fine.

The garage quoted me £120 for a replacement spider sourced through a Fiat dealership. I turned this down though since the OEM part is available on Shop4Parts for a fraction of that (£28.45 inc VAT and shipping) so I've ordered it from there on their behalf.

Thanks to you all, especially MikeG20. Without speaking too soon since I haven't got my car back yet, this repair job has cost significantly less than I previously feared.

Update #2 : Got my Bravo back this morning. It feels like a new car again. I've never been so pleased with it. All in all, the total cost was £92 (£60 labour/grease, £32 for the spider). Again, thanks everyone.

Great. Im glad you solved that problem

Vibration under acceleration

Hello All,
I have vibration problem as well. At higher speed (~100mph) the frequency is higher which comes through the steering wheel as well and even felt in the chassis through the shoe sole.
At low and very low speed it is felt also, but the magnitude is smaller and its frequency is lower and almost nothing is felt through the steering wheel.
So, disregard what speed the gearbox is, it is present.
Some level of the vibration always present, but gets worse when accelerating and climbing up to the hill.
Differential side (inner) drive shafts were changed as well as the tripods. So both, left and right complete sets with necessary high temp grease.
The issue is still present. Tyre is not an issue, summer set and winter set produce the same.
It is a T-Jet Sport 150hp with the M32 gearbox.
No whinning noise what described in many topics.
If not the inner drive shafts, what other issues or known weakness of the drive system could generate it? Sometimes it gives the impression that it is more feelable when longer trips are performed and the car well reaches the operating temp.
The odometer is at ~160k km
Thanks in advance for Your help.

Re: Vibration under acceleration

How many km has past since you changed tripods/grease?
Vibration also could make worn (outer, wheel side) CV joints

Re: Vibration under acceleration

the left side inner was changed 10k km ago and the right one just now.
The outer joints were not yet changed. According to the mechanic, this vibration is not outer joint origin.

Has this cured your issue?

No, not yet. It is still a pending issue.

Ok... thanks for that. I seem to have vibration and rumble low down in third, fourth, fifth and sixth... that's if i drive like a grandad / taxi driver at then try load it with boost... too low rpm and i get a rumble... all be it the stilo 150 multijet tuned... hoping its my tripods...

On mine T-jet it were inner "cups/bowls". Exchange of tripods was not enough.

In the Czech Republic there is a specialized repair shop of Mr. Mihalik. You can google "Mihalik poloosy", I am not allowed to insert links.

The refurbish of the cups was 9000CZK (approx. 350e).

9000CZK is way too much for refurbishing. At its half price you either get the left or right as a set.

Dear All,
By now it got clear that the tapered bearings are in a pretty bad condition. The tapered rolls' surface show remarkable pitting as well.
This is the cause of the vibration.
Some questions:
There are bearing rebuild kits on the Ebay for the M32 gearbox. Does anybody have any experience with those stuffs? Lifetime, reliability?
They are advertised as rebuild kit for M32, but at the "list of vehicles" the T-Jet 150hp is not mentioned. Can I order it with peace of mind that will fit even if the Opel/Vauxhall types are mentioned and the Alfa 159 ? Nevertheless the headline clearly states the M32.
According to the Owners' Manual, the 75W-85 oil is recommended. Is it worth to change for 75W-80 or the original is good as it is?
I know, the fillment must be more than 2.4 lit, rather 2.9 or so.
Thanks in advance

That will not cause vibration... maybe some sound... but if you have gone this far yes, it is worth replacing the bearings.
When i was researching for a friend a few moths back they all seemed to have the exact same bearings..one seller even had a message similar to this:"don't bother asking if it fits your car, if you have the M32 gearbox it will fit, regardless of the make/model" .... I would of course ask the seller before buying.

Cheers for that, man. I can't believe how rare these parts are. My local garage is reluctant to take the shaft apart to determine precisely what the root cause is, so I was tempted to go down the refurbishment route. I found a place that will take my existing unit and recondition it in around 2-3 days and quoted £135 including shipping to and from. (Driveshaft UK)

Realistically, I think I'm only going to be keeping the car for another 1-2 years once I get this sorted (If I'm lucky) since it's becoming rather troublesome. This wouldn't normally be an issue, but considering how scarce replacement parts are, I don't have the temperament to deal with this sort of wild goose chase on a regular basis.

Just had the driveshafts replaced on my bravo, for anyone reading this National Tyres replaced both driveshafts the whole units for £395, then their website has a 20% off voucher to use which made it £315 including labour. Bargain if you ask me. For going to a garage.

My car is now cured, for info it was done on 1.9 Mjet Sport.
