no not really :grin:
It holds the engine up so you need to support the engine while you do it, I'd replace all the bushes on the wishbones and anti-roll bar while its off, if you can I'd go for an uprated ARB too since the only time you can swap it is if the subframe is dropped :)

well the rear subframe is under the engine, the rear axle is what the rear wheels are attached to ;)

u know i always call it the wrong thing, so how hard is it to do??
rear axle subframe thing i mean lol

ok, 1st you gotta disconnect the brake flexi lines & rear presssure compensator.  I'd chop the flexis then you can get a socket on them later on, then replace with goodridge lines later on.

Then you need to remove the large axle pivot bolt, and the lower suspension bolts then the beam should drop down.

sounds ok to do, so wots the catch??
Title: Re: rear subframe
Post by: rubjonny on 12 April 2007, 16:23
brake lines being a sod to remove, brakes being a sod to bleed once done, main pivot bolts being a sod to remove, that kind of thing ;)

Post by: dubslug on 12 April 2007, 16:28
just had brake lines done not so long ago so that bit should be ok, one man blled system gonna be ok??
can i not just undo the two 17mm bolts that holds the frame on?? thats wot guy did with the one ive bought
Title: Re: rear subframe
Post by: rubjonny on 12 April 2007, 16:32
you still need to disconnect the flexi lines, as all the solid lines are clipped to the beam & rear calipers!

Post by: dubslug on 12 April 2007, 16:37
bugger, so ill still need yto bleed system after ive finished??
reason for change is ive bought frame with poly bushes fitted already
Title: Re: rear subframe
Post by: rubjonny on 12 April 2007, 16:59
if you're canny you can drop the beam enough to drill out & swap the bushes without disconnecting the brake lines, its tricky but doable :)

Sorry to hack into the thread but I'll be doing my rear axle bushes before much longer and wondered if there was a list of parts that I would need to complete the job as I've done a few jobs lately and ended up getting stuck when I've had to go without the car untill I buy more bits that I didnt realize I'd need when I started the job. Is it best just to get a new set of axle bushes from GSF ? I dont mind if I end up with more bits than I need I just want to make sure I can finish the job once started, also is it worth replacing any other bits on the rear suspension while I'm at it as the old girls starting to sag a bit on the rear end   :undecided:

for the rear beam if you go for OE items they need to be pressed in by a garage, poly ones just press into place with a bit of lube once you've hammered out the old ones.  Get the full on replacement poly bushes from Rally Design though:

You wont need any more parts apart from replacement axle beam nuts as I believe they are self locking ones.  Unless you break anything dropping the beam ;)

i was always told to steer away from poly bushes on the rear beam and was also told to re-new the axle nuts, as rubjonny said.

OE bushes help with the golfs passive rear steer. Gives better turn in and helps prevent the rear end breaking away too suddenly with lift off oversteer.

you'll be fine mate. i think you'd only notice a difference when really trying hard  / on track.

Post by: dubslug on 12 April 2007, 22:55
ah thats ok then, this frame was already bushed up and cost me a huge 20 quid, might crack on with it tommorrow

It depends who you speak to about poly bushes, a few people recon OE are the best, but theres plenty of track day warriors on cgti who rate them, and they don't drive carefully :cool:
Title: Re: rear subframe
Post by: Uruk Hai on 13 April 2007, 10:34
I think after reading all the posts I'll go for the ones that are easier to fit (poly), hopefully I'll be able to do them without completely removing the axle from the car.

dubslug, let us know how you get on mate ?

have just done this job, the old bushes are a pain to remove, i would not attempt it on the car! i found a good way was to angle grind the big end off then get the biggest drill bit you could fit between the outer metal of the bush and the metal sleeve in the middle and drill the rubber out, then hacksaw through the outer bit. polys go in easy though.

rally design sell the poly bushes for about a tenner each  :smiley:

 Where do you put the axel stands when you remove the rear beam? as I allways put them on the beam :huh:

^ Good point ?
Title: Re: rear subframe
Post by: VeeDubGTI16v on 18 April 2007, 20:54
think i put them just inside the sill by the front of the arch, theres a nice strong looking bit sticking out

yep that is the correct point for a trolley jack/axle stans :)
