Hi all
Sourced a second front recovery hook from an interstate wrecker, unseen, for my 2004 Patrol wagon.
Arrived today. Not what I expected – probably ok – dunno?
On my Patrol, the original hook is bolted to bottom of chassis rail along the rail centre. . It’s basically a straight bit of solid metal tube bent down and around, with 2 large bolts connecting it to a thread welded inside the chassis rail.
The one that came today fixes to the side of the chassis rail with a plate, to which a hook (similar dimensions to original hook) is welded. The plate is bolted to the chassis rail with three bolts. Definitely solid. Rail has threads inside the rail – same bolt size – correctly positioned – Definitely must have been made for a Patrol. Thing I don’t like is the line of load will be eccentric to the line of the chassis rail – i.e. will generate bending forces (a ‘moment’ to the engineers out there) around the weak axis of the chassis.
Any thoughts?????
JD

Hi JD
I can understand your preperation for futcher towing requirements of Said Nissan re = Motor Problems.
However most Tray Top Tow Trucks can back in and roll them up No Poblem.
Unless of course you intend to go out the bush then they will not have the most up to date tow trucks.
Just incase you need it towed a long way may be best to weld it on ?.
Regard's Jon

Mate this was a serious question. Why dont you go
check out a Toyo website or something - might have a
forum discussion on recovering vehicles with broken diff's or something. LOL :-)))))))))

I agree...... with Grandpa joe and jd!
How about a serious answer to a serious question.
If you're going to 4wd, it makes damn good sense to have recovery gear in place, NO MATTER WHAT YOU DRIVE!

Isn't this the same guy - "Goingplatinum" that rambled on about 3.5 litre Nissan engines a few days ago?
I think he's one of our American cousins,,,,,,,,
I may be wrong, but the reply is a bit sarcastic.

Gday JD mate while i aint no engineer i have to agree the line of load dont sound right but mate why the need for another recovery hook is there a fault with the original fitments i should know about because when you say metal tube bent yep sounds weak as put that way
but obvoiusly the nissan /toyota thing is alive and
well
i think another forumite sums it
well with "when all else fails buy a nissan"
Cheers

"when all else fails buy a nissan" - couldn't agree more Barney - very happy with
mine.
Look no problems to speak of with the existing hook - Nissan hook about as heavy as any Ive seen. But we have been involved in quite a few serious snatches - e.g. recovering others and being recovered ourselves in deep mud. I'm conscious the load all going down one side all the time cant be that good - so want to spread the load where I can. I also like the idea of using a lanyard (??) , particularly after seeing a strap let go on a video (referred to on EO a few months ago). JD

The thing to remember is that with 2 recovery points on the front, and assuming you will use both as often as possible, the new one will cope with anything you give it because it will only be taking half the load.
Does that make sense?

jd patrol mate you can buy the original tow hook from nissan dealers but will have to order in cost about 40 $ as i recall but you have to source the HT bolts from a bolt store to bolt it on on the other side with the threaded holes are in place - i did this - the one you have from the wrecker is probably ok but
check the welding real close
any torsion loads will depend on the angle of the pull so and yes in simple terms if the pull is at an angle will both try to shear the bolts and pull them out at the same time whereas with the original hook position its all basically a shear load - if you were to hook both ends of a tow rope or snatch strap to both hooks should all be ok - but hard to say without really seeing it - and yes i am an engineer civil usually
but mate that other dopey wank@r is a real DH is he not
see you greg

thanks Greg. Yeah, get a bit tired of the Nissan knockers.
Gees I was quoted about $100 by my local Nissan place, which is why I sourced it from Wreckers. Bugger
Welding looks good. We'll see eh. Regards JD

I would not use a welded hook. I have been involved with testing recovery hooks and we found that some welds have crystallised the metal and caused the hooks to snap. Forged hooks 'unwind' (straighten out) when overloaded which is better then having a chunk of metal fly through the air. Also, use grade 8.8 bolts and no higher. The higher the tensile rating the more brittle the bolts become.
A new forged hook should cost less then $20

no worries jd if the welds are good and its bolted in with three bolts say 12mm size or larger then it all sounds like it should be ok to me - no cerification though with out seeing it

I got a 2nd recovery hook put on by my Nissan dealer during a 20,000 service, I said how much and the mechanic said "carton of beer". Not sure whose car they took the hook off but I was happy!
