Thread: Groan upon full lock

if anything like the d1 setup then usually it is the pump cavitating or the power steering unit.

check the pump without belt and make sure it doesnt have end play ie the pulley moves in and out by more that a millimetre or two.

you can bleed the old oil out of the system and fill the system with new by opening the bleed screw on the top of the power steering unit while someone slowly moves the steering wheel from side to side... make sure you keep the fill bottle full.... you need engine running of course..

fixed it in my d1...

make sure you use the right oil...

Id expect that the fluid is full of air (milky and full of small bubbles.

This can be caused by a number of things, low fluid level, small hole in a line (accompanied by a slow leak normally), Loose fitting/s or crimps.

a. flush the fluid as Inc said
b. repair leak

Beggered bearings normally are accompanied by a grinding noise all the time, the noise you describe sounds like cavitation caused by air in the system.

The D2 has a problem with the reinforcement inside the chassis rail near/at the steering box mounts. The rail flexes slightly on full lock & creates a groan/creak against the reinforcement. There's a bulletin issued for a fix.

It involves drilling a hole or two in the rail & plug welding to secure the reinforcement section to the rail.

It's quite a common complaint so it might be the cause of your problem.

SCOTT!!

You have just solved a frustrating mystery for me!

I have a D2 with the same complaint, and I swear it is INSIDE the chassis at the steering box! I even tightened the steering box bolts, which were loose, and it made it worse!

Thanks mate, can you possibly supply me with the bulletin number? or a pic/ instructions on where to drill etc?
(This vehicle was dealer serviced etc all its life until my customer just bought it, and the noise has been there for a llooongg time according to previous owner)
I just Luurve fixing this stuff!! Give me a MIG welder and a die grinder and I'm a happy little vegemite!
Thanks muchly!!

I'll dig out the info on Monday. There's a template as part of the bulletin so it's a relatively easy job.

Thanks mate. Anyone know where I could get this mod done in Melbourne?
