Hi, I've ben a long time lurker here, and have enjoyed reading all the posts, I've had my Three-wheeler for a few years now, and recently i have noticed that my steering rack appears to be getting stiff, by that i mean after turning a corner the steering wheel does not come back to center, when its cold and for the first few miles its is almost normal, but as the engine warms it gets progressively worse, i can put it into a good corner and take my hands of the wheel and it will stay turned into the bend, i have to physically turn the wheel straight again. I'm assuming heat from the engine or bearings somewhere is causing it, has anyone experienced this. Thanks in Advance,

Is steering stiff when the front is off the ground on axle stands?

I haven't tried that yet, I'm abroad working at the moment, but when i get home i guess i could try it cold, then take for a drive and try again to see if there is a difference

The corrosion (rust) of the steering rack may be the cause, or the front axle lower ball joints worn.

I had this after it was left overnight in the rain, there is a hole in the body of the steering rack close to the centre.
I believe it is used for steering alignment purposes.
To ease my stiff rack, with the front on axle stands, just dripped in some light oil into this hole and worked the steering back and forth, repeating on a few further days.
After a couple of trips it was back to normal.
From a tip from Phil Bleazey I fitted a section of slit plastic pipe over the rack so covering the hole.
No problems since.

Covering that hole sounds like a good thing to do. When i first spotted it i was wondering why it was left open to the elements.

Indeed if you check Phil Bleazey's post at Re:_Steering_rack_rainproofing it sounds like you may have fallen foul of Morgan's rack positioning (ie the hole letting water in...)

Thanks for the replies, I'll be trying the oil in the rack when i get home, and post if it helps

I put Millers EP140 in mine, same as the bevel box. Lock to lock smooth as silk.

I have worked up a cover for the holes. I have not gotten the rack back into the car yet but this fits perfectly and would keep out all debri nd water from the rack. It clicks into place and is solid on the rack. You could get more cautious by adding band clamps, but as yet I am not sure the clearance in the vehicle.








I will try to add a video of it clicking into place.
