Talk Morgan Forums Morgan Sports Cars Classic Morgans (pre-CX) EZ Power steering disaster, car almost undriveable

One other thought - since you are in Ashbourne, you could ask Langley Classics to take a look at it for you.

They resolved a major wiring problem for a fellow DonMog member and I know that several DonMog members use them for servicing. And it won't cost you a fortune in petrol to get there.

I would ask them to put in writing that car steering shouldn't self centre.
Or to name a car with no self centring.

looks like there's a replacement shaft and bugandymog has it fitted. So burgandymog if you can provide a measurement and picture of said shaft to Nmog perhaps that might start to shed some light on the problem.

Will do later. Mine was fitted by MMC it was the press car first +4 fitted with EZ and it self centres.

First pic 24 cm between joints.

To add further confusion Dave there are three UJ's on steering if later cars. The one nearest steering wheel to accomodate vertical adjustment of steering position. On my car the yokes of second two are not aligned having an offset around 30° and it steers fine with the help of factory standard EPAS below, as fitted to Toyota Aygo, Peugeot 107 etc. This differs from the requirement for a transmission propshaft



There is a useful pdf download available here explaining phasing of UJ's on a steering shaft.

Whilst the yoke offset found on my car aligns with article, turning steering at wheels to accomodate greasing whilst on ramp I can still feel steering wheel accelerating/decelerating a tad.

Yep! That's the same as mine too Richard but without the power steering of course.

Follow up post after doing some research. This is the EPAS motor on my August 2018 car Jon. Would be very surprised if yours in not the same.



The Denso 995-10500 is also fitted to variants at least of Toyota Aygo, Peugeot 107 and Citroen C1. In each case they employ speed sensing input. MMC's wiring schematic for both 3.7 Roadster and GDI Plus 4 show a cable on four pin EPAS connector, present if employed or not, receiving a feed from pin 11 on BCU. I cannot imagine this being other than the speed signal which is distributed via CANBUS and available to BCU. Whilst the Denso EPAS will function without this signal it then defaults to full assistance at all speeds meaning the steering would be extremely light at high speeds possibly more so on a light Morgan. This makes me extremely sceptical of the advice you were given by MMC and possibly explained by there being more than one EPAS system used on our Roadsters.
