just ordered my marlin seals two days ago ,i too am doing the minitruck knuckle upgrade and 4x4 labs high steer . I hope my knuckles are close also i have no sst. .see what happens i will keep my fingers crossed. preload is easy.
it's just hoping it is centered on the housing.
will let ya no if mine leak. i ordered 4 seals .2 for spares . it's a hassle getting these things sent to Canada.
