So after rebuilding an 80 series steering box and reinstalled it I found a lone ball bearing!
So it must only have 43 balls in there. Is this a problem and should I pull it apart and put the last ball bearing in? Eg will it cause “slop”?
Pain the ass!
Cheers
If you're finding you have to screw the adjusting screw in quite a lot to try and remove "play" then it's possible your gears on the sector shaft and/or the power piston are worn. I've been doing quite a lot of research on recirculating-ball Steering gearboxes and if the gears (teeth) are worn...
I’m after the one with PPS (4412060190) but I could just swap the bits over from that one assuming they’re the same input shaft, power piston etc etc l… Thanks for showing me that. It’s pricey but cheaper than a whole box.
That is what I was worried about. Thank you for that.
Unfortunately Toyota discontinued the power piston/valve assembly so buying that part new isn't an option anymore.
Because it was wearing in a certain part of the teeth, between that wear and the original/untouched surface there is a lip or bur. Run your fingernail over the teeth and you'll see what I mean. All 3 spare boxes I had have this.
When you add a new sector shaft to a worn power piston the metal...
Has any had any luck filing or grinding the teeth on the sector shaft and/or power piston teeth to make gears mesh smoothly and take any play out? Especially removing any burs or ridges which can cause binding.
I have a few spare boxes and they all have play where the teeth mesh, but bind if...
Gday, yeah I replaced the spindle with a needle bearing type. Much tighter tolerances!
I had already done this on the other side, so I've got both sides with the newer needle bearing spindles now. Much better.
*update*
Well I tore it down and replaced CV and spindle.
No more sound. Nice and tight. Fixed. 👍🏻
I actually think it was because my old spindle was worn a bit and the CV axel was rattling around. when the axel was under drive tension (between diff gear and drive flange) it didn’t move...
Absolutely no play 3/9 or 12/6. New genuine driveshaft unis recently too (sound was there before and after).
There’s plenty of grease in there!
I mean I guess it could be pinion slop but why only on a certain rotation? And it doesn’t sound like it’s coming from the diff… it’s in the end of...
Gday brains trust!
Wondering if I can get your professional listening opinion on the following…
Front feft side is making a driveline clunking sound ONLY in a certain rotation of the wheel/axle.
First video shows the noise on a certain part of the wheel rotation.
Second video is when the...
Already done all that thanks.
The play is up and down.
The lateral play is normal and the c clip is fine.
The later model spindles have roller bearings and my other side already has this. So I’m thinking the old spindle has just got to the point it’s chattering due to 300+k of wear…
Yep. If I hold the axle and bash the tyre, no noise. Or if the axle is torte (from diff to drive flange) there’s no noise. BUT if the axle has slack movement it rattles. And that’s what must happen when I’m turning and hit a bump on that side.
It’s 100% the axle retelling around in the spindle...
front right axel seems to rattle around. You can hear it when you go over a sharp bump
I’ve tested it by holding the axel (birf) and giving the tyre a good hit.
So what could it be?
Worn spindle? Worn drive flange?
I found an old 14mm hex nut that was a bit longer. Drilled out out and it works well.
As the adjusting screw needs to swivel around I wouldnt be inclined to tighten it down or you won't be able to turn the adjusting screw. So I'll fit it lightly and put some loctite on it.
Hope this helps someone:
