Repairing Rear Spring Turret on GQ

Submitted: Wednesday, Oct 03, 2007 at 07:14

Willem

I had a mate drop by from Darwin on Monday and he just had to find something wrong with the GQ.(Maybe because he drives a Handgrenade...lol) After peering into the engine bay for a while he grabbed a tarp and slid in under the chassis and sure enough, he found a hairline crack on the right rear spring turret. Bugga!!

Now to repair!

1. Grind V-shape into crack with angle grinder. Wrap Alfoil around spring and Poly-air bag. Make sure there are no leaks from fuel tank. Lie on back with suitable protective gear and weld crack

2. Jack vehicle up high with Hi Lift Jack. Stabilise on Jack Stands. Remove stabiliser bar, shockabsorber, spring and Poly-air Bag. Remove Turret(not sure if this is possible as no mention of turret is made in Manual) and then repair and then put the whole lot back together again. Painful job!

Any better ideas?

Leroy,

It sounds like they based the "handgrenade" on Willems GQ LOL

Unreal them Nissans eh, seen one at Wolfe Creek Crater , He told me he had to go to the Granites Mine off the Tanami to have front Diff/axle housing welded , and when I got a long way down the Tanami Track I come across a Nissan parked up , not a soul in sight and the whole front axle assembly taken out , and it was sitting on blocks, the disc rotors and coils in the back ,Had a damn good ARB bullbar on it too,

Drill small holes at ends of crack (if accessible) to arrest cracking and monitor area -- it may have been like that for years?

Unfortunately it is not unknown on GQ's but more common on GU's especially when fitted with heavier springs and carrying a bit of weight.
In an extreme situation they tear off the chassis completely and crush the brake and fuel lines up against the floor. A friend had this happen to his GU in WA while on hols and it was a very expensive body off the chassis repair.
I'd be drilling the ends of the crack as suggested and then trying to get it welded in situ by a competant welder.
It may require removing the rear diff housing and running gear to enable better access, the last resort would be either lifting the body up enough or taking it right off.
When they repair the spring towers on the utes they weld a length of RHS across the top of the spring towers between the chassis rails to stop the towers flexing up on the inside, might be a bit hard on the wagon though, depends on how close the floor is.

Yep. My mate is going to make up a frame to fit under the body of his GU so that the flexing stops on the turrets. I do know that this could be an issue with GQ's.

I will drill a small hole to arrest the crack to start off with. It is accessible. I have not carried great weights in the GQ and now have transferred all the weight to the trailer. The back of the vehicle is very light. I do have the poly-air bags in the rear and run them at about 10psi. The truck has done 346,000km so the few repairs I have to do now are minimal.

Hows it going guys ,

My next door neighbour had the same body off experience with his GU . As you said a real show stopper on the wrong side of the country , Noticed on your member profile you are in the TLCC Peter, may be the same guy he is a member as well.

There were a fair few posts a few months ago on the chassis / spring mount crack topic . Many blamed airbags , but dual wheel carrier type bars also got a hiding .

I reckon I would give the in situ fix a go before major surgery , The worst that can happen is it will crack again . At least you will be able to keep your eye on it.

Yep I will give the in situ a whirl first. The crack is only about 5mm long at this stage. I know a bloke who is a good welder so will ask him to help when I see him next.

Have you solved the starting problem with your GU yet?

Yeah , changed the glow plugs.

Starts first time now on cold mornings.

In hind sight it used to do a smokey start every now and then and I was thinking maybe the injectors were needing a service. I guess it never got cold enough to be a real problem.

Hope you sort your crack out.

Glenn.

It will need plating, or it will crack alongside the weld.

Willem,
Got a panel beater mate who suggested you empty the fuel tank, run compressed air into the filler to help vent fumes. Tape a fire blanket to the tank adjacent to the welding area and use someone as a spotter.

Cheers....Lionel.

Wayne (NSW) replied:

Willem,

If the crack is only 5mm long, I would drill a 6mm hole to get rid of the crack all together.

A 25mm square plate could then be welded over the 6mm hole.

You would have to get the 6mm hole in the centre of the crack or go for a bigger hole, or

If possible I would try and have a small steel plate on the inside of the tower where the hole is and weld the plate through the 6mm hole. Grind the weld flush with the outside of the spring tower, this should stop the crack from spreading.
