Quaife IRS diff problems

[RMS Boxer Service]

I've got a new Quaife IRS diff and i've encountered some problems when fitting the stock CV joint
flanges on the outputshafts of the diff.
The splines are a little looser than a stock VW diff splines and the flanges are sitting deeper into the
side cover compared with the stock diff. On the stock diff there is a compression washer thats preload
the flange against the circlip, but when fitting the compression washer there is no preload and the
flange can move axial on the splines.

Am I missing some washers or should we just leave it as is??

I just make up spacers on the lathe, to replace the VW ones.
Not too thick though,
just enough so I can still get the circlip on easily.
Very likely they will be slightly different side to side too.

Had the same with my last quaife irs...made also thin spacers...
very sad from quaife to let the customer alone with this bad / unfinished construction
happy that other solutions are available who support all required parts with the diff

Thanks for your replies. It's a shame that Quaife either have finish engeered product or
a solution for the problem.  I have Emailed them twice before I even got an answer that
they got my first Email and was working on it. Still no answer 2 weeks later....

I ended up with two modifed stck washers in each side.

Are anybody having issues with the Quaife swingaxle diff??

Oh yess,but very few people will admit there is a problem...

Ask some big names ...those who run "long distances",not the "trailerqueens" ...

I tell you one thing; Swingaxle diffs like the quaiffe one,are running "dry" on long runs,the oil just doesn't get where you need it; inside the diff,inside the diff-bearings and between the fulcrums...

You need to modify the diff with oil-channels,spraybar into the case or individual oiljet sprays from porsche-engine,use a good external 12V oilpump with a small oiltank,and spray that oil into it...

Good luck!

Hello Steve..

Even Quaife?
they are mostly used in endurance races/ circuit racing, sounds strange to me ...
Super diffs on the other hand....

A swingaxle diff is different stuff then a IRS diff ,the bearings suffer big time on the swing/Quaiffe Diff.

I'm just talking about what i've seen in person,i can show 5 different tranny's with the quaiffe swing/setup that had damage on the axles,fullcrums,and the diff itself where the fulcrums are located.
These were all trannies from guys that "drive" their car,no trailerqueens who can claim they 're running a BERG 5 speed...

Been in touch with Quaiffe UK for 2 years before they stepped up their game...

Yess the super diff's aren't good either,say worse...

Not many VW bug owners drive their cars regularly. I’m one who does, but I have more than one car so don’t accumulate many miles on any of them. How many miles does it take to cause that kind of wear? What type and viscosity of oil are you using?

Stock VW LSD´s had this problem too.
I wonder if the approach VW made themselves on 181 transmissions would make the difference.
I have recently modified a sidecover like that, but no testing yet.

that can work to lube the bearing more from the outside. I did it just last week on a cover. easy to machine. can't hurt to do it in my opinion.
