budgetbondbile Posted November 12, 2019 Report Share Posted November 12, 2019 (edited) I've noticed on my driveshafts think the o/s I'll double check, there's a piece of rubber integral about halfway along it that seems to be 'disintegrating' is this like a dampener or anti-vibration thing along it? has anyone any experience of this? And does this mean it's gonna snap at some point? Cheers in advance for any help Edited November 12, 2019 by budgetbondbile Link to comment Share on other sites More sharing options...
rich_p Posted November 22, 2020 Report Share Posted November 22, 2020 Digging up an old post, and I’ve not been here for a while myself, but I have pretty much the same issue as described above. I could hear the rubber flapping against the ARB when rolling. I’ve trimmed it off to stop the noise, but does anyone know what the rubbers actual function is? It just seems like plain metal underneath it. I think the only fix would be a new driveshaft, which is tempting anyway, just not sure crucial it actually is. Can anyone advise?

You can send off your drive shaft to get refurbished, and it should come back with a brand new rubber on it. I do believe it is for anti vibration damping. I'd rather have it than not. 1 Link to comment Share on other sites More sharing options...
budgetbondbile Posted November 28, 2020 Author Report Share Posted November 28, 2020 Yeah thanks, can't really see how it's supposed to work, don't know how crucial it is, most cars I've seen, particularly on o/s have had similar wear, only thing is in that state it's prolly only gonna make vibration/centrifugal forces worse, don't know whether it'd be better cutting em off?

Dan1zz Posted November 28, 2020 Report Share Posted November 28, 2020 Took them off on mine, just cut the rubber and wire wheel the rust off. not had any issue with vibrations. 1 Link to comment Share on other sites More sharing options...
budgetbondbile Posted November 28, 2020 Author Report Share Posted November 28, 2020 Cheers, yeah I'm not sure how they're supposed to work exactly, but they do look unsightly more than anything else Link to comment Share on other sites More sharing options...
ams Posted December 29, 2020 Report Share Posted December 29, 2020 I pulled the rubber part off mine when it came loose and left the metal bit under on it and it was fine , see loads of cars where the rubber has come off - probably more didnt have it than did to be honest.

Cleario Posted January 4, 2021 Report Share Posted January 4, 2021 I cut mine off on the recommendation of the old boys in work, they said they’ve seen water sit under the rubber causing the shafts to snap on the corolla’s and Avensis. 1 Link to comment Share on other sites More sharing options...
_Chris_ Posted January 5, 2021 Report Share Posted January 5, 2021 It will be a vibration damper for the same reason as dual mass crank pulleys. Any spring plus mass combination (and metal is springy) will resonate at a particular frequency. In the case of driveshafts, this will be a certain speed. If kept at that speed constantly and without the damping, the flexing of the metal will lead to fatigue and snapped driveshaft. The big question is what speed is the resonance, and how long do you spend driving at that speed. A very informative thread on the subject. http://www.gt4dc.co.uk/forum/viewtopic.php?f=13&t=6120&hilit=resonance Link to comment Share on other sites More sharing options...
Cleario Posted January 6, 2021 Report Share Posted January 6, 2021 I can agree on the crank pulley 100% the hybrid Engine still have a ‘damper’ pulley fitted which is a normal crank pulley but they don’t have any aux drive belt/components, it’s sole purpose is as a damper.

Seen loads of corollas/ versos/ avensis that have rusted and snapped under the rubber. But on the celicas never seen one snap and when ive taken the rubber and ciut the metal part off completely they havent been rusty underneth. Its another example of the difference in component / build quality that Ive seen with european vs japanese built cars. Have you found the same? Theres loads of small things ive found over the years to be common on euro built cars compared to jap built cars that have put me off them.

_Chris_ Posted January 8, 2021 Report Share Posted January 8, 2021 Having come from years of owning escorts and talbots as my toys, I noticed a massive difference in the quality of steel used by Toyota, both for body metalwork and fixings. On a ford, a body panel would go from a stone chip to a hole in a year or 2, and leaving any surface rust when repairing would mean doing it again within a couple of years. Very different story on the Celica. Likewise bolts which have been there for 20 years just take half a turn with a breaker bar and out they come with fingers, very different from bolts which are rusted solid within a year. This is why I always clean & re-use original bolts rather than fitting new aftermarket ones. Even plated bolts rust quicker than original Toyota.

Corrosion on sills/wheel arches, lower arms corroded with holes in. All made within the EU. Yet we still get Prius taxis in with 250,000 totally original parts. (Minus HV batteries) I actually brought this topic up at the academy (we do Lexus and Toyota training even though we have differnt techs working on them) and was given the answer of ‘There’s a reason Lexus mainly produce cars in Japan’ (and look at the old RX that was made in Canada) On the other had the hilux and land cruisers produced in South Africa rust. Badly. I know they’ve had hard working life but I’ve seen 2016 with brake backing plates corroded, snapped coil springs, floor panels with holes in, all super common problems. we’ve obviously got the airbag inflator recalls still going on, I’ve done a few starlets/celica’s recently still solid maybe the oil leaks stop the corrosion Edited January 8, 2021 by Cleario 1 Link to comment Share on other sites More sharing options...
ams Posted January 8, 2021 Report Share Posted January 8, 2021 Do think it’s pretty amazing that Toyota are replacing the inflators on air bags on 25 year old cars when officially the service life was 10 years. Link to comment Share on other sites More sharing options...
Cleario Posted January 9, 2021 Report Share Posted January 9, 2021 I do but also can you imagine the bad press that would happen should a 20 year old Toyota sending shards of metal into an innocent driver. I’ve worked for a certain brand that after 10years airbags are advised they get replaced. When replacing them curtain airbag bolts have snapped, fallen out but it’s always been kept on the low. im not sure what I can openly say without causing myself problems but I’ve worked for 3 brands all of which use Takata airbag inflators only 2 of them have an active recall. Toyota take any safety related items seriously from the floor mats, we have to remove any non genuine floor mats, we have another active recall for CH-R /new Corolla brake pedal torquing to the air bag inflators. I’ve done a few avensis that have had driver, passenger and Airbag ECU complete replacements, easy £1500 parts plus 2.5hours labour. In all fairness I think Toyota need more gratitude for being completely open about it and are more than willing to admit the error(from supplier not in-house fault) and will replace them at no expense to the owners. 3 Link to comment Share on other sites More sharing options...

I say this whenever I hear people say "OH look toyota has another recall - not as great cars as you keep saying" Great example is the window switch recall on the mk2 yaris at 10 years old. VAG window switches break after 5 years and they have done for years, same as there window regulators which have been the same shitty design for over 20 years! Add to that door looms breaking after 3 years and the dealer not being able to supply them as there is a 3 month backlog - yet they deny there is a known fault. Even the oil issue on the 1zz - the VAGs had a 1.6 engine around the same age and that was awful for oil burning - and it wasn't down to gummed up rings like the 1zz (which I blame on lack of maintenance /. wrong oil) Link to comment Share on other sites More sharing options...
