Mathew Rimmer Posted June 27, 2007 Share Posted June 27, 2007 As title says. Its a ZF LSD from road and race (ie modified for caterham) approx 5 years and 20k miles ago. How do you know if its working as it should ? (more scientific method than do-nuts) Read an article on GT3 diffs requiring rebuild every 10 trackdays and that got me thinking. thanks Link to comment Share on other sites More sharing options...

dannylt Posted June 29, 2007 Share Posted June 29, 2007 Send it back to them for a refresh/rebuild? Will be cheap if it's mostly ok. Or more expensive if it's full of shrapnel Link to comment Share on other sites More sharing options...

Mathew Rimmer Posted June 29, 2007 Author Share Posted June 29, 2007 Probably 70:30 road and track. I too thought they would be long lasting, but was surprised at the Porsche stats, albeit they are somewhat more lardy and with a tad more power.

Graham Perry Posted June 29, 2007 Share Posted June 29, 2007 I don't recall many folks complaining on here in recent years about diff failures ? Link to comment Share on other sites More sharing options...
stevefoster Posted June 29, 2007 Share Posted June 29, 2007 You can check this See http://www.our-nest.co.uk/Caterham/html_files/2005_lsd_adjustment.htm for how you can also put one wheel on some wet grass and give it somebeans - diff should lock up and off you go...

Gambo Posted June 30, 2007 Share Posted June 30, 2007 MIne started to spin the inside wheel. Then I knew it was knackered. ☹️ Full rebuild was about £500 including parts(lots of them) RED 2.0 HPC 230BHP here Link to comment Share on other sites More sharing options...
