Redline Shockproof HD
Posted: Wed Apr 04, 2012 9:03 pm
I wanted to pass along a data point on Redline Shockproof HD in the wheel drives.
I had some free time today and did a lube change on the 4 wheel drives with Redline Shockproof HD. I'd used their shockproof stuff in a couple of motorcycles in the past with surprisingly good results. I have to say I was quite shocked (and I am fairly shockproof myself) at the drastic reduction in gear noise.
I probably did not get every last bit of the existing oil drained out since I could not get more than about 1.25 quarts total into the wheel drives (book says I probably should have gotten another .5 in at least if they were drained).
I will have to wait and see if there is any seepage, but this is pretty thick stuff that is roughly as viscous as the 80/90 wt. Below 50kph I am hard pressed to hear any of the spur gear noise at all, and above 50kph it is apparent at about a quarter of the dB it was before (sounded like a jump to light speed), and still very, very reduced.
I will probably do the front and rear diffs in a couple of weeks, then figure out if I want to try the shockproof light (which is supposed to be ok for the syncros) in the two gearboxes.
A big plus from my perspective.
