I have a 71RR that I just completed a full restoration on and it has an annoying pop in the front end. The pop mostly occurs on left turns and seems worse if there is a bump during the left turn. The pop seems to be coming from the driver's side. Everything is new in the front end. It has a Bob's Profab tubular K member, Firm Feel stage 2 steering box, Flaming river tilt steering column, Firm Feel quick ratio steering arms, Moog balljoints and bushings and all new steering linkage parts. I torqued everything in accordance with the service manual. I greased everything on install then after I noticed the pop so everything should be well lubricated. Any ideas what I may have missed or what I should check? Thanks for the help!

Double check all fasteners, bolt's etc..
Reading your post makes me question a shock bolt , DUNNO

that'd be my start. was the suspension loaded (at ride height when the bushings etc were finally tightened. As you know something is loose/moving when under stress

also look at your castle nut under tie rod or linkage arm?

I thought I had mine tight enough, finding it was way loose after.

just a thought -

go grab a buddy and jack up the front end of the car
and take the weight off the front suspension.
then have him move around the tire up and down with a bar and side to side
as hard as he can and while he is doing that, look for exessive slop or play in the front suspension or steering linkage.
alot of times the problem will be easy to spot.

Did you grease the torsion bar ends?

Thanks everyone for the replies!

I am not sure that I greased the torsion bar ends. What parts of the torsion bars need to be greased? Thanks

the front/rear hex ends

Is it possible to get them properly greased without removing the torsion bars?

no cuz they fit into the matching hex recesses pretty tight. EDIT If you do undo em be sure to measure the ride height on each side before so you can get it back to that exact height so as to not alter your alignment specs

I had a rattle in the front end every time I went over a bump. Thought for sure it was shocks or exhaust hitting oil pan. Drove me crazy cause I couldn't find anything wrong with shocks, exhaust or suspension. Turns out the joint that connects the steering shaft to the intermediate shaft was worn and the intermediate shafts was bouncing around.

Yesterday I removed all the cotter keys and made sure everything was tight in the steering linkage. I snugged up the shock bolts and strut rods also but the pop is still there. I took the car for a drive and I was able to get the front end to pop even when going straight by loading and unloading the suspension so it does seem that it may be the torsion bars. I lightly lubed them when installing them but likely did not lubricate them well enough. I will pull the torsion bars this weekend and grease them up and see if that takes care of the pop. Thanks for the help.

You might shoot some WD40 in the hexes just to see if it quiets em, likely would not last forever but that'd confirm that it is the tbars as it'd be better than tearing em down/greasing & then them not being it but there is a good chance it is them but I'd sure give it a shot. EDIT if you do undo em dont forget to duplicate the ride height exactly so you dont mess up your alignment

I pulled the torsion bars and greased them last night but the popping noise is still there. I had a buddy come over today and turn the steering wheel so I could observe the steering linkage in action but I did not see anything out of the ordinary. I watched the steering shaft and steering box while he turned the steering wheel and I did notice the steering box input shaft moved in and out as it was rotated back in forth. The link to the video below shows the input shaft movement. The back and forth movement shown in the video is the slack in the steering box which is almost a 1/2 turn of the wheel before the pitman arm moves either direction. What is your opinion on the input shaft movement? Thanks

I think we've ID'd the problem.

Glad you found it. And even though it may have been unnecessary now, you'll be glad that you got grease on those torsion bars in the long run

That want exactly my problem so I can't comment on that end play maybe someone else here can

Repeat the test with the wheels on the ground and the motor running as the hydraulic pressure may eliminate the end play. IF not time for a steering box.

That's a good idea, I will try that this afternoon. I was reluctant to think it was the steering box since it is new with only about 50 miles on it.

Check for cracks around where the k frame mounts to
