Rear springs Add-a-leaf

Postby Growlerbearnz » Mon Sep 18, 2017 12:17 am

Lately I've noticed that the caravan has been sitting a little nose-up when towing, when I'm sure I built the Delica's tow bar to tow it absolutely level. I think my rear springs have sagged a little.

Add-a-leaf kits are easy for more common 4WDs, but not for the L300. I ended up buying a Toyota Tacoma kit because it was cheap, local, the centre pin is offset like the L300's springs, and it has nylon anti-friction pads (unlike some cheaper leaves). This one: http://www.trail-gear.com/product/4854/tacoma-rear-add-a-leaf-95-04

It still needed to be shortened a little at one end, and a new hole drilled for the plastic pad.

The existing spring leaves have dimples to help locate them. I had to grind off the dimple next to the new leaf.

Reassembly was uneventful.

And now it's up on stilts. It should settle a little, which will be nice.

I'm not quite finished. The differential pinion angle has always been a little high (4-5 degrees higher than the transmission). The new springs have helped by about 1 degree, but I'm going to install some wedge shims to correct it properly. The spring packs are also mounted with a couple of rubber isolating pads. I had to remove one of the pads to make room for the new leaf (cargo vans don't have the pads, so it's ok), but I think I'll buy new, longer U-bolts so I can keep the rubber pads as well as the larger spring pack.
Nothing says "poor workmanship" more than wrinkles in the duct tape.

Growler, I am making a trip back down to southern California soon and will be stopping by deaver. They manufacture custom leaf springs and have been in the industry for ages. Already spoke to him about re-arching my spring pack as well as a heavy duty add-a-leaf. I'll post up some more info when I get down there .

Good idea! I looked into having my springs refurbished here, but the cost was NZ$500 a pair. Cheaper than buying new ones, but more than I expected. Something about being the only spring manufacturer in the country or something? Yay New Zealand! It's pretty, but it's small.
