Rear Leaf Springs Squeak, Squeak, Squeak....

Thanks Joe, I have tried fish oil but aftter 100km of dirt the squeaks return, I will try the Innox and lanotech. The ute sounds like a removalist van with the sqeaks....

Phil,
Stock standard issue from Toyota. Chris

Hi Chris,
The factory spring bushes are rubber with a metal sleeve; the rear shackle upper bush is rubber only.
I'd jack up the rear chassis, leaving the wheels on, undo the rear shackles, slip some black moly grease inside the sleeve on the spring and some rubber grease inside the rubber chassis bush, and see if the noise goes.

Thanks Phil,
I will give this a go next weekend. Chris

Hi Chris,
I noticed above that you sprayed the springs with fishoil. Fishoil is not a lubricant - it's used for rustproofing steel, as it penetrates, dries hard, and is sticky.

I suggested doing the rear shackles first because they are the most likely cause and are relatively easy to do. If you need to lube the front shackle bolt, they are easily removed but can be hard to get back in because the propellor shaft pushes the axle housing back a little and the bolt holes no longer line up - I use a puller on the rear axle housing to pull it forward if I have this problem. I'll assume that you've checked the tightness of the U-bolts.

The leafs themselves normally wouldn't squeak, but your lanotec would sort this out. Best way to get leaf springs working again is to remove them, undo the centre bolt and disassemble the pack, clean them all, smear grease over each leaf, reassemble and put back in. Not too many people do this - it takes a bit of time, but the ride improves a bit.
