Default Update

I found a U mount under the steering wheel, I tighten those bolts and the steering sleeve that was loose tighten right up👍 I ordered 2 new bearings for both ends of the sleeve. I think while I have it all apart Iíll do that upgrade that was posted on here. Hopefully I can figure that out. Still learning here but thanks for all the help. You guys are great. SPM

your problem is the billboard tires... FACT. I had the same issue, I installed better tires (avons) and problem solved... I still cant understand why anyone would run those crap tires... They look cool but horrible tires...

I agree the Billboards wont drive as smooth as radial tires but the steering wheel shake was happening with my goodyear 17 inch tires on it. So far i was able to tighten that upper steering sleeve, and found the steering wheel bearing disintegrated. Next week i should have all the parts for the beefed up steering linkage to the rack. Cant wait to test drive it and see if its better. Those Billboards are like that real pretty girl you date that you know shes trouble but you have to date for a little while Maybe AVON’s next?

Received all the parts but when i installed the linkage it seemed to bind on the lower u joint connected to the rack. Its seems like the angle from the upper u joint needs to be higher for it to turn without binding. I checked the invoice, it seems to be the correct u joint. Any ideas Thanks Sean

Are your u-joints phased correctly? see page 7
http://www.woodwardsteering.com/PDF/...d%20Shafts.pdf
also you can loosen the steering rack mounts and tilt it slightly aft and it will pretty much center the lower steering u-joint which pretty much make the upper u-joint the only one bending.

Please post pics.

Size:  91.8 KB[/ATTACH][/ATTACH][/ATTACH] It was late and I got frustrated with the new linkage so I put the original linkage back and just went for a test drive. The steering shake is gone. Must have been the loose muffler clamp under the dash or the bearings in the steering rod. But itís riding great now. I still want to get the new linkage installed. I like the idea of tilting the rack to decrease the angle for that joint. I took some pics of how it was when I installed it last night. Thanks for that post about the phasing I never thought of that. Tilting that rack should do it. Sean

Looks good.
Last thing I'd recommend is adding a divot (with a sanding drum or grinder) to the the ends of the Double shaft, and a drilled divot to the upper splined shaft for the set screws to lock into. Last thing you want is to pull back on the steering wheel and the shafts disengage.

I’ll do that once I get the setup figured out. When I loosen the 4 bolts holding the rack, will i be able to rotate it or do I have to do something else. Looks like it should rotate. It would be nice to get it so that lower u joint is straight or close to it. Would you recommend welding those DD’s?

The rack rotates with not a whole lot of effort. Easiest with a deepwell socket and extension slipped over the input spline. As the input shaft tilts aft the distance between the two universals get smaller and you'll have to shave the double-d shaft.

Welding the lower double-d should be fine. I'd skip the upper due to the chance the vibration damper could melt.

I won't be welding mine as I have a heim bearing support in the center.

Great, thanks for all your help. I’ll do this tomorrow. I notice those bearings are cheap plastic that are on the steering tube. What you think about putting metal ones in their place. Got to be something better than plastic that could really keep that steering shaft tight. When I take it back apart I’ll mic them and check around. Or maybe I’m over thinking this and live with what they use

Yea the BMW shaft bearings are not that great. They are thrust bearings and work better with a face load (sorta like a wheel bearing). If you can have someone push the steering wheel towards the the front of the car with about 10lbs of force (loads the aft bearing) and you slide the tube retainer against the forward bearing as you tighten the set screws. That should remove any axial & radial play in the shaft.

Now that you mention it, when I first installed mine the DD shaft was set to far into the knuckle (that attaches to the rack) causing binding. I had to adjust the shaft, so that the knuckle could spin freely.

...and a coat of paint to all (unless you picked up the SS DD shaft).

I loosened the 4 bolts and can’t get it to turn. I then loosened the tie rods thinking that might be the reason. No luck Has anyone else tried turning the rack so the lower u joint would have less of an angle.

Sean, Can you loosen the hardware enough gap in the pillow block clamps to see if someone over torqued the bolts, distorting the rack tube? (It could be oval shaped)

I got it to go aft about 20 degrees which was enough for the u joint to turn without binding. I just tightened everything up and went for a test drive. It’s like a new car. Turns really nice. It was worth the time and frustration to get that new linkage to work. I almost bailed on it. I glad I hung in there and thankful for all your guys guidance. I’ll post some pics when I get a chance. Maybe this could help someone else. Thanks again
