Sloppy rear shocks mounting shaft

[Gnickgsmith]

Hi,
I am rebuilding my rear suspension and have discovered the mounting shaft that fits through the wishbone to mount the shocks on is a very loose fit in both the wishbone tube and the shock absorber bushes.
The shock bushes are relatively new - probably less than 500 miles. If the wishbone tube was sloppy and the shock bushes tight I could understand it, but both sloppy with one being 'new' is a mystery.
Can anyone advise me please whether this is normal or I need to machine a new slightly oversize shaft to fit?
Everything else on the rebuild had being going so well!
Thanks very much,
Nick

Hi

It sounds like somebody has fitted the wrong part, or made something on the quick.

You need part number C17013, available from most parts suppliers at around £23 each. You'd be advised to fit new nuts too.

If the part you have is as loose as you say the rear end would be knocking quite badly.

Stuart,
Thanks very much.
Makes sense.
I've ordered the parts!

Although, having thought about it, somebody may have drilled the wishbone tube oversize.

Let's hope not.

Nick what diameter is the shaft you have?

[Gnickgsmith]

Not sure the diameter but it’s the same as the shaft which connects the wishbone to the diff - as in diameter. I’ve ordered some new ones so if they are sloppy too I’ll have some slightly oversize ones made up too full the hole’.
Thanks for everyone’s advice.

The shafts are 5/8 (0.625in).....they are not a tight fit through the tube on the wishbone where the shocks fit there is some movement (befor fully tightening).....Steve

Steve,
Thanks. I may be over worrying. New bits on order and used the old ones as dummy shafts for the main fulcrum shaft! So not wasted.

I used 15mm long wooden dowels as dummies for the main wishbone shaft alignment..using metal dummies could damage the washers..just a thought

15mm copper plumbing pipe works great......and has an advantage that the thread on the fulcrum shaft slots in the end of the copper so sliding the shaft through is much smoother.....Steve

And if you use a 15mm pipe splice cutter it puts a lovely radius on the cut that helps guide it through.

Ooh...nice

Final post from me on this and thanks for everyone’s input.
Turns out you do need a bit of movement and the wishbone has clearly been designed for this. When all bolted any slight slip goes. Slop was only there without the shocks so was clearly overthinking it!
Happy days,
Nick
