I'm about to start the same job, but with full legs. Basically to replace a bodged job done years ago, so it's much harder as very few spotwelds to drill out, plus I replaced the floors without thinking the legs really needed done too.

Just a few bits done over the weekend. A couple of bits painted and red oxide on the finished welding.
I'll put the suspension back this week then underseal the drivers side and jobs a goodun.

I had to rethread the lower pin, I must have been a bit heavy with the hammer when I took it out.

All good now though.

:) Carried on stripping and cleaning the front suspension today and found the track rod gater off at the bottom clip.

So I took the rubber off and made sure it had no grit inside or play on it.

IMG_20200318_141226.jpg


Everything looked OK so I cleaned up the rubber and the old grease out.

I also took the grease nipples off and cleaned them out, then put it all back together.


When putting the new bushes in I found that the top pin didn't pull all the way in.
Something I didn’t spot earlier.

On further inspection I found that, previously, someone has jammed a piece of metal in, presumably to tighten a slack pin.

I've left we'll enough alone, it's tight so will out last me.
Tomorrow I'll hopefully get it all back together.

Keep the updates coming 8)
I've got to say your exploits have urged me into action on my traveller after a long lay off. Spent the last few days working on the rear chassis and correcting a few mistakes I made. It's not pretty but it's getting there :D

Got most of the suspension together, which was all guess work.
I marked everything when I took it apart but cleaned everything so all the marks were gone. I'll readjust it at a later date.

When it came to the tie bar, with new bushes there was no way I could get the yoke bolt in.
It was too far back to line up.

After taking out the spacer behind the yoke.

And straightening both the front bush washers.

IMG_20200319_141139.jpg


And using the old manky bushes, the tie bar only just went in.

IMG_20200319_140859.jpg


I'm not quite sure what to do about it yet, other than trim the new bushes down to suit.

IMG_20200319_133946.jpg


Any thoughts would be much appreciated.

Rubber bushes are much better for the tie bar than poly bushes.
Poly bushes hardly compress, while they are a good alternative for a rotating bush, that isn't how the tie bar bush works, poly bushes at the tie bar (as you've found), particularly cheap ones, don't allow proper compression making them difficult to fit.
I put a set of green poly bushes on my Traveller when I restored it, and around 2 years later I found that they were so hard that one tie bar bracket was bent from bearing the brunt, the other was fractured, both legs had been replaced at the time of restoration.
It is normal with new tie bar bushes, even rubber ones, to compress the bush slightly by means of the end bush nut (easier to use a normal 5/16 BSF nut for this rather than a nyloc) to line the holes for the tie bar yoke.

Thanks for you comments Chesney, it's much appreciated.


I've ordered some rubber bushes, while I'm waiting I decided to look at the wheel bearing, it sounded a bit 'gritty'.

It was.

IMG_20200320_123807.jpg


The inner bearing recess was in good condition,

IMG_20200320_133048.jpg


but the outer was a bit scored, I don't think I did it, the marks looked old and the outer race was tough to get out.

IMG_20200320_133112.jpg


So I cleaned it up with a half round file and emery cloth.

IMG_20200320_140104.jpg


Then ordered a new bearing.

Put the new rubber bushes on today and the tie bar pulled in a treat.

The new wheel bearing is a different matter though.
I put both the new bearings in but the hub had play on it, no matter how much I tightened the hub nut, it just wouldn't pull in.

So I took the hub off again and took the bearings back out.

I did find some burrs that I missed in the recesses which I ran over with a Dremmel and miniature disc.

IMG_20200324_131728.jpg


I put the bearings in the opposite way to previous because I noticed that they have a slightly chamfered edge on one side so tried that edge first.

IMG_20200324_133039.jpg


It made no difference, the inner coned sleeve is not flush against both bearings which is causing the play.

IMG_20200324_135052.jpg


I am at a loss at the moment as both bearings seem to be fully home.

Comments are most welcome.

All bearings offered by suppliers (maybe it's changed now) that I have used have all had more play in them than the ones I've taken off, do a search, it's fairly well documented.
I know we're all (now) in lockdown but the best solution I found was to take the existing bearings to a bearing shop and ask them for high quality replacements, never had an issue after that.

Thanks for the input Chesney and Panky.

I’ll phone the supplier tomorrow and get their input.

I did consider making a shim to take up the play but wanted to get some input first
