Title: 5stud / plus suspension conversion
Post by: thai-wronghorse on 01 February 2014, 20:21
I posted this over on UKmk3's Facebook page but I'm left with a few uncertainties now so thought I'd ask here as well before i dive into it this week...

So the wagon has just been for it's first MOT in my ownership and failed on a few bits as I expected it to tbh, especially as I've hardly touched it since i bought it a couple of months ago.
Anyway the combination of sh!t brakes and potholed damaged tyres means that my 5stud conversion courtesy of the 16v will need to be brought forward as i refuse to pay for crap I essentially already own.
I've done a fair bit of reading up on the swap but was wondering if you guys had any tips worth noting to assist with the transition?
The doner 16v has ABS, my TDI estate doesn't. Also the 16v doesn't have a rear pressure regulator...I think the wagon does? (not checked yet)
I've been told my regulator won't be of any use as it was designed to be used with drum brakes but why would that make a difference?
Also im getting mixed opinions on using the track rod arms, many threads mention to swap them but a couple of people have said it's not necessary...obviously if i can get away with not changing those as well il be happy.

Parts i'll be transferring are:

wishbones
hubs
discs / calipers / carriers
driveshafts
anti roll bar (what's the easiest way to remove this?)
track rod arms (are these a straight swap?)
rear stub axles
handbrake cable
master cylinder
wheels

Is there anything I've missed out?

the brake pressure regulator should be fine if its adjusted properly.

Well that's what I was always lead to believe. I really dont want to start chopping up the brake lines either to make these work properly.  Its been many years since I tinkered with car with a pressure regulator on the rear beam, how do you set them up with the correct bias?

found this which is pretty helpful.

What about abs? might be a pita but well worth having if you uprate the power, and you already have it

As much as i would like it im not sure i can arsed with fitting it tbh, that would mean major brake pipework and wiring surgery and the car would need to come off the road for longer.

Yeah I know, I couldn't just throw it away if it was me :grin:
Most of the pipework is there and you will be swapping the master and brakes, that's the easy part.
Question is does the wagon have ABS points already in the loom or is it cutting and joining in etc etc, that would be the fag in my opinion and the place enthusiasm might evaporate :grin:

Post by: thai-wronghorse on 01 February 2014, 23:07
Correct me if I'm wrong but isn't the ABS wiring entwined with the nearside dash to engine loom? Because if that is the case there's f**k all chance of me even considering it after seeing the wiring carnage in my 16v at the moment.  :shocked:

ABS aside, im still unsure if i'm going to need to swap my track rods over. I've just been trying to cross reference the part numbers on both cars and im stumped as there are variations on which rack the car was fitted with eg. TRW or ZF
I'm hoping they should be the same though seeing as they're both late mk3's with PAS....or do i just need to change the track rod ends to suit the 5 stud hubs?

Offer them up and see what happens, its not to much work to try them on

Yeah i'll just get everything whipped off the 16v, cleaned and prepped up and see how it goes. It's just nice to have all the knowledge up front of what I'm about to undertake as it's inevitable that they'll be hitches along the way - there always friggin is!

Another informative thread, about half way down the page my track rod issues are answered I think.

i would change the rear bushes on the gti rear axle as you are going to take it all off its worth doing
Title: Re: 5stud / plus suspension conversion
Post by: thai-wronghorse on 02 February 2014, 00:25
I wouldn't considering the rear beams are different and I'm not taking it off anyway. The rear bushes on the wagon are staying for the time been seeing as they've literally just passed an MOT and I've got enough to do without adding to the list. :rolleyes:

My car had an mot last week i think the mot tester went a bit mental my advisories were.

Both front brake flexi hoses slight cracking
Both rear bushes deteriorated but not showing excessive play
both rear brake pipes slightly corroded
o/s passenger rear floor slightly corroded (was told under sill is coming off but no rust ? )
Both front top mount bushes slight play
N/S/R wheel bearing slight play (its a new bearing just needs to be tightened up a little)
Jacking point slight damage
Both front outer sills damaged (twits of previous owner jacking it on the seals)

My previous mot had 1 advisory track rod end the previous owner had the car then my car has done 6000miles since last mot my mileage is 116k people are saying bin my 16v but I know its little jobs to fix my car i will keep it

tie rod ends don't change bet_een racks but the tie rods do, tr_ is smooth and black and zf is silver alum and is not smooth (inprinted into the rack)... it's more common for the VR to have the zf and other less models to have tr_

b.t. the _ key dosen't _ork on this pc

Ok cheers il bear that in mind when I start pulling it all apart.

Another thing that has been brought to my attention is the rear anti roll bar. Im yet to familiarise myself with the estate rear beam but I struggling to find any real info on it online at the moment.
Obviously il be changing the front one but im not too sure what to do with rear and there doesn't seem to be many aftermarket choices even.
Would the GTI ARB transfer over...even if modified? How about the mk2 Golf or Passat parts bin?

Having now removed all the required components from the front end of the 16v something that has got me thinking is how to go about transferring the ARB correctly onto the TDI without damaging anything as obviously the sub frame was dropped on the 16v but this was without anything left in the engine bay?  :undecided:
Im guessing ideal I should have an engine support beam attached whilst dropping it but I cant really afford £80 on one of those at the moment, any suggestions appreciated.

A good bit of 4*2 and some ratchet straps, notch the ends to clear the wing lips.
Got me out of trouble a few times, may need to unbolt some crap on the top of the engine to clear
Title: Re: 5stud / plus suspension conversion
Post by: Bellend on 13 February 2014, 15:28
If I was you I'd drop the entire subframe down and swap it.

Up to you whether to swap PAS racks but it will be the simplest/quickest way if slightly more awkward.

You will need the outer CV joints from the 16v which will slot straight onto the Wagon driveshafts.

I've done this conversion myself.

Regulator will be fine if adjusted properly which can take some fiddling.

How well did this transformation go in the end then?

I am planning on doing the same, I have a 2.0 petrol GL estate (I think its a AGG engine from an 8v GTI or similar) and the brakes feel like treading on a mushroom, they are shocking!

Did you transfer across the rear ARB in the end?

Also can anyone explain the tie-rod differences a little more clearly (I had to get a mechanic to change one on my 16v when I bent one on holiday and I suspect they may have put one in that is the wrong size, the thread had to be all used up when the car was tracked).

Much appreciated,

Adrian
