Outer Limits 4x4 Board

Heys Guys


Had a search and a look through the bible but couldnt find any info on replacing the upper and lower trailing arms on a GQ.

Are they just a simple press in and press out deal? (Ive got a 40t press at work)
Is there anything to look out for?

Were going to just grab some normal replacement nissian rubber bushes (if the dude from superpro dosent ring me back)
Its only a 2" lifted mild tourer.

Cheers

Spot on. Pretty easy to do.

Do one arm at a time so the diff doesnt move too much.

Use a little WD40 or similar if they are stubbon/help getting new ones in.

You will need an appropriate size socket/pipe to press them out/in with.

Use rubber bushes, better ride/flex. Have heard of poly bushes being quite noisy too.

Press in press out may, piece of cake. DO NOT use any lubricant to press metal shelled bushes in, they are an interference fit.

Sweet. Thanks for the info guys, Much appreciated.

Ended up getting the superpro bushes, Should have them in by the weekend.

When installing my last set of bushes. We ran the outer rim around on the grinding wheel very slight just to round the edge off. Also used copper grease or anti seize. Makes the next replacement a little easier. As my first set had to goto an engineering place to push them out. As the 20t wouldnt have a bar of it.

the outer shell of the bush is very thin so you need a perfect sized dolly to push them out.

you can try sanding down an old bush shell enough to make a loose fit inside the trailing arm then use a flat plate on top to push it evenly on to the bush you need to remove.

Agree with the others, the poly bushes are no where near as good as the genuine rubber bushes.

Just thought I'd throw in a tip, you can make some good simple bush press tools by finding some ally pipe the same diameter as the bush with a decent wall thickness so it sits on top nicely. Cut it to the same length as said bush and then using a 1mm cutting disc, cut a diagonal into it. This means when u press the bush out and the tool is in the arm it will have that 1mm cut to compress making it slightly smaller and easy to push out. Ally is the best because it won't damage the bush. Also don't be fooled with fleabay " genuine rubber bushes" they not genuine and the factory Nissan bolts are loose inside the bush, I use an ally coke can to wrap around the bolt to take up the slack that china bushes have. Otherwise they flog out prematurely.

I cant complain about mine. The new ones should take some high rev launches at the drags a bit better. I heated my trailing arms a bit with an oxy set. Couple of taps and the old bushes were out no worries.....

just did another set of bushes in my truck today, another tip i find helpful is put a jack under the tailshaft, i put it on the ring behind the uni's and that rotates the diff around so you can perfectly line up the holes when putting the bolts back in.

The coke can trick isn't a bad idea. Would it work for a pepsi can too?

If you put your new bushes in the freezer for 24 hours they will be just that little bit smaller and will slide in easier.

If you really want to make it easy heat your arms a little as well and the bushes will almost drop in.

Hey Guys.

Thanks again for the replies. Replaced them all today.

Did them one at a time while the car was on the hoist. Piece of cake.
However the old bushes (sleeved rubber ones) took a bit of grunt in the press to get out. Just took abit of time to make and good setup for the press.

Id been told by my mate who's car it was that his mechanic reccomended he change them soon. He saw the quote then due to work and lazyness hadnt 'gotten round' to it.
The bushes were absolutley flooged though. All but one the crush tube had seperated from the bush and was bouncing around the bush

The Superpro bushes being a two part thing (bush and crush tube seperatley) were easy as to push in once all the old crap had been cleaned out of the arm.

Didnt see that respnse till after i changed them. Great idea though.
Becasue the car was on the hoist i just used a heavy duty ratchet strap to get everything lined up sweet.
