still stuck on sj410

[SIMONJACKSON]

help still needed
brought sj410 of ebay oops
have now sourced another transfer box fitted all works ok but now when put in 4wd low and the diff locks locked in makes a horrible noise as if ball bearings are grating topgether any ideas

[baz2236]

Does it do this in 2wd ?
 have you check the Props are not loose ?
have you got the same size tyres on front and rear ?
check your diffs
have you check there is oil in t-box and diffs
you should'nt really put it in 4wd when on tarmac as it can cause wined up

jack all 4 wheels up and turn the wheels and see what happens.
