Evo 4 AYC oil change

[B6lee]

I sorted my abs which I only knew was a problem once I put the bulb in the dash. Then the ayc stayed on but I don't get enough traction. Keep spinning wheels cos the rear diff is runing open when ayc not working :sad:

No good. Aint that bad for the diff.?

Not when you spin up a rear wheel in 3rd going round a very slight curve it aint no :shock: No it's fine cos all fluids still where they should be. Will be sending pump off for overhaul end of the month anyway

That wont be cheap

Prob not, and I need tyres so by fixing the ayc the tyres will last longer cos I won't keep spinning one all the time.

 

[m7gsr]

you'll prob. have to change both rears due to the uneven wear
what size tyres you need?

You could just try putting a pressure gauge on the pump to see if its low on pressure, and not operating the rear diff strongly enough, or a faulty solenoid not letting the good internal pressure out into the diff.

I did a search on Google for a "AYC pump Tester" and rented one from an MLR trader for a week for £20.
Pump was actually fine, but it was one of the solenoids was staying jammed in after being operated, not letting out the Juice when asked. Its a sealed system so hard to spot whats going on inside the pumps, as the mut test just showed all was good electrically, but the ayc is a hydraulic pressure system, and grit or corroded pumps dont show up, unless you take the time to check the output end too.

Hope that help, Chris (newbie on here!)
