Popping/grinding in steering when turning

[rmkilc]

You are around 16 months of using this and notice no noise? I would be curious to see your results after this amount of time has passed and the wear level on your fix.

I've been doing my best to try to isolate this popping noise I started having after a new K-member/control arm/inner tie rod were replaced as a result of a wreck. Later had my axle on my driver side replaced as well and this noise is still present. Only thing I can narrow it down to is the washer/bushing that you have figured out.

Correct, no noise after 16 months and about 16,000 miles. When the OEM bushing separates so the rubber and metal washer are no longer one unit, the washer slides back and forth and gets caught up at an angle on the teeth of the rack. This is what causes the noise each time it gets hung up on a tooth and is forced until it slips off.

Even if my method eventually fails, since it's all plastic, there should be no noticeable hang up.

As promised, coming back here with resolution. Hold my beer.
Here are the parts I purchased:
Amazon product ASIN B01N1P0T20
Worked like a charm. I first installed one spacer, put it back together and tested, it was not enough, so I put second
stopper, that was Perfect. So I ended up with 2 spacers on each side.
Spacer spec is as following: 6.5mm depth, about 23mm inner, 32mm outter diameter. The great part is that its plastic and meant
to spread apart.
The passenger side shaft is 30mm, inner diameter of the rack tube is about 47mm
The driver side shaft is 28mm, inner diameter of the rack tube is about 47mm

Here are various Ford spacer part numbers I found
N804842-S Steering Limiter - 6.5mm <- this is the ones I bought
N808506-S Steering Limiter - 10.65mm (blue)
N807853-S Steering Limiter - 2.4mm
W705003-S Steering Limiter - 4.25mm
W705004-S Steering Limiter - 7.25mm

Unfortunately I dont know original thickness of the limit stoppers, so best I can guess is that they are more than 6.5 mm and less than 13mm.

Here are pictures of the completed job. Spacers fit snug, I snapped them right after inner tie rod at the outer edge of rack.
They stay in place and not gonna move anywhere.

I am fully confident in this repair, feel free to spent $15 on 6 spacers, vs $1500 on a new Rack.
Nice job Ford.

Thank you very much for this. Did you have to remove the inner tie rods to do this or did the stops just spread open to slip over? Also, I know this is a very old thread and I came across it.

Mine broke years ago and I haven't bothered getting the rack replaced. I just make a sharp turn slowly and there's no popping noise, also making sure not to turn the wheel to it's limit. Since then, no issues.

No point getting fixed.

No inner tie rod removal for any stop like this that can be spread open to slip over the rack.

Thanks. Also, this didn’t last long did it?

I didn't use that style for very long. I would guess for long term they won't hold up.

I know this post was a very long time ago, but I am intrigued by the possibility it raises. My 2013 Explorer Limited with 70k miles exhibits the exact symptoms you reference in your comment. I recall having a 90's Pontiac Bonneville which made the same sounds. Turns out the problem was rusty strut bearings. I had an out of state shop check the Explorer a few months back and they suggested a bad rack, and said the sound seemed to be internal. I wonder if they overlooked this other possibility. Thanks for making the post!!
