I put Nulon G70 into my rear differential a few weeks ago and within 2 x drives in the ute the diff whine on the non- drive hypoid gear set is noticeably quieter. The ute has nearly 300,000klms on the clock. Non- drive is when you come back off the accelerator pedal. I have put some in the manual transmission but havnt driven enough yet to notice any benefits yet. I have been very happy with all Nulon products I have purchased. Excellent quality

Has definitely improved the noise of the diff. Also had fast and efficient delivery through the post.
Great additive for any manual gearbox. Have used many times before
I have been using Nulon in my gearboxes and diffs for years. Definitely makes shifting easier and my Coaster bus now has 440,000 Kms and is running as quiet and smooth as ever - even after towing 2 tonne across Australia. Gives me great peace of mind.
My old 80 series Landcruiser (350,00km) 5 speed manual gearbox was not shifting well from 1st to 2nd gear and was "notchy" on all other gear shifts. Drained old oil, added a 250ml tube of Nulon G70 Smooth Shift and filled the transmission with Penrite ProGear synthetic 75W-85 (GL4 grade). The difference was immediate; like night and day. The shift from 1st to 2nd was far better and all other changes are almost as good as new. Soooo much smoother........ If your cruiser manual box has the same issues would expect you won't be disappointed with the results.
My O7 Falcon recently developed an intermittent whining sound when coasting . So I had to find a quick solution and this product worked immediately . The feeling of the car was instant freedom , it rolled free as a bird right away and the annoying sound vanished . Great product . Nulon is an amazing fix to an otherwise expensive diff rebuild .
I used this in my 05 wrx, 3rd and 4th were crunching pretty bad even after an oil change so I thought I'd give this a go (albeit apprehensive using fixes in a tube.) It worked literally instantly. Crunches are completely gone and gear changes feel like a brand new gearbox. It's not think and glue-like as a lot of additives seem to be. Hopefully it doesn't turn to sludge and ruin the gearbox, I suppose only time will tell but at this point I'd use it again!
Bought on special and thought I’d give it a go.Smoothed our the gearbox Noticeably. Manual 12 year old 3L D.$23 and threw in 2/3 of the big tube (equates to 3L of oil on the gearbox).$23 worth definitely well spent.
