Rear lower trailing arms

Post by **mtb4x4mad** » Thu Nov 06, 2003 7:59 pm

During the past weekends' wheeling, we managed to break a rear lower trailing arm and also twist an upper arm mount. As we didn't realise that this happened immediately, we also twisted the diff around and snapped a pinion and wrecked something inside the diff. Has this happened to anyone?

By the way - this was a Nissan Patrol GQ wagon.

Very common thing to happen. The tubes are thin as, slightest dent in the tube ruins the structural rigidity and any compression will cause the tube to fail. Diff rotates under drive, until the ears of the uni bind and act as a lever to snap the pinion.

it happened to a mate he also bananaed his shocks and took about 4 hours to get back to level ground so it could be loaded up and towed home.

you probably buggered the shocks as well.
www.wizardperformance.com.au sell stronger trailing arms.

If anyone wants to make stronger arms from scratch, here is the results of some digging around looking for steel sizes that I have done lately.

Onesteel sell a circular hollow section that is 60.3 OD and about 5.3mm wall or something close to that, it gives you the perfect ID for the OE nissan bushes or the poly aftermarket ones.
Schedule 160 and XXstrong grade seamless pipe are both around S160 for a 6 metre length in 42.2mm OD Schedule 160 is a bout 7mm wall and XXstrong is about 9.5mm wall.

For anyone that was curious the material thickness of standard upper's are only 2.5mm :shock:

.........So i would assume that the lowers although there a bigga od have the same wall thickness hence y they always bend

I extended my uppers 2night after puttin in my lift ................just a pointer wen rotatin the pinion angle just make sure that b4 u do this cut the back off the bumpstop bracket so that u dont end up with a ding in ya new shockies like i did :oops:

.......Wendle has posted this b4 and iwas aware of having tocut it off but was goin to do this after rotatin as i didnt realise just how close it was with a very small lift :cry:
