castor arm movement?

[tanz-e]

hi people, can i have some help please?
ive got this knocking noise coming from under the drivers seat somewhere... turning corners seems to aggrevate it as well as bumps in the road... today i turned a corner quite heavily, pushing the car into the chassie and maaaaan did it knock... just once, as the centre of gravity and my chassie met....

im wondering: is it possible for you castor arms to move so far sideways they knock against the chassie?*

im fairly sure its the castors, dew to dirrection of noise. aslo ive checked my shocks, springs tie rods steering arms, tailshafts, uni, gearbox and transfer case mounts, engine mounts-(one was stuffed, since, both have been renewed), everythings real nice and tight...

there is no visible scratches or marks in the dirt on either the chassie or the castor so its got me stumped.....
*no sway bars

do it worse in the wet? i had a similar problem in my old shorty and from what i read on hear it was old body mounts. sounds like somethings knock on the floor below your feet yeh?

check you body mounts , better yet just replace your body mounts as it is pretty hard to see anything wrong with them

not sure if its for better or worse in the wet havent done enough driving in the wet to test. it doesnt rain enough... but it was raing today wen i was driving it around as mentioned earlier, but i dont think it had more of an effect...
body mounts...
thanks guys ill look into it.
im sure they've never been replaced since 89...

+1 for body mounts .
I had the exact same problem ( large knock under your feet ) .
new set of body mounts and you'll be sweet .

Go through and tighten them up first before you buy new ones. Had same problem.
