The MTB forks were starting to make come knocking sound and I thought it was about time that they got a service. Was expecting to see some wear on the stanctions, but they are in perfect condition.
Because of the knocking I thought that the bushes might need replacing, but on visual inspection and by feeling the upper bush, appear to be in good condition with no obvious lip or rough edges.
Although I have not opened up either the dual air system or dampner system, neither were leaking oil at the top (Need some snap ring pliers to have a look)
The dampner shaft moves in very freely though.
Any suggestion on what could be causing the knock, other than worn bushes, and I'm pretty confident its not the headset as I did tighten this up to see if this got rid of the knock, it didnt.
Any ideas on likely cost to get just the bushes replaced.
Thanking in advance.
