Rear toe arms - same across all models?

Post by Icsunonove »

I mean the arms at the rear of the rear suspension that you use to adjust toe settings. Anyone know if they are the same for Mk1a, Mk1b and SC?

Seems that they are Tom, not sure if the SC is different again.

I was always under the impression that mk1a are different. Not sure if the actual components are different but the inboard end is certainly located in a different position and I'm pretty certain that this gives rise to a different total length for the link.

EDIT - EPC has different part numbers for mk1a and b as well.

Cheers Chris :D

I'm going to attack mine later with a a gas burner and a huge pair of Stilsons! :mrgreen:

Just wanted to know that I'll be ok if it all goes Pete Tong.


EDIT: Cheers Phil. (Still going to have a go at freeing them off. Want to borrow alignment and camber gauges from the MR2Challenge lot at the weekend and check and adjust it if necessary)

lol, i just answered in the pm didnt see this.

the 1a's are shorter than the 1b's (or is it the other way round :-k )

the centre part i believe is the same, the 2 ends are different.

should have read the post above first #-o

Yeah, sorry Tim, my fault.

Right, would anyone else be interested in a group buy to have some turnbuckle tubes made up in stainless?

If there is I'll do a drawing and get a price. Everyone I've spoken to has had problems with these stupid things.... :roll:

Would this include for the 1a or exclude?

Blimey your bearding knowledge is poor.

the MK1a's are quite a bit longer than the MK1bs.

An SC is a MK1b.

therein lies your answer.

Well I've never owned a 1a, so how would I know?

No, it could include. I'd just need someone to measure one up for me and I'd do a drawing.

We might be interested in these for both the 1a, 1b and SC :mrgreen:

Tom, I have contacts for lifting equipment (stage rigging) which often utilises turn buckles. Resiliant to rusting due to outdoor use :wink:

I would just need to have a closer look to see if what we used for rigging would be suitable for the cars :-k

Which is why I ask the question else it would be needless...

...which is where your assumption errs

Let me expand to make it explicit rather than implied:
Would a version for the a be available as well as for the b since they are of different lengths?

I see Tom and System-G have already answered... thanks...

One of the features of the 1a arms is that the two outer pieces lap over each other inside the centre tube to keep the outers from rotating when you adjust the toe. Nice design feature but when both sides seize on the tube you cannot free off one at a time (I learnt the hard way). I suspect the 1b arms don't have this feature because of this problem.

i knew one was longer, i just couldnt picture which car was 8-[

there is a possibility of a design change in order to prevent the rotting/rusting. i'll chat it though at mallory tom.

I had this problem last year mine were totally siezed up and ended up snapping of one of the overlapping ends of the rods. A nice design feature if there was space to fit it in would be a grease nipple mid way along the tube.

Arrggghhh! :evil: Right, I give up. Tried soaking in penetrating fluid, heat and loads of torque and still no joy. Just put them back as they were. It should be right because I paid Toyota to check the alignment and they confirmed it was right. I hope to borrow some equipment from the MR2Challenge lot to confirm.

I will start a new post to see if people are interested in getting a batch made up in 304 or 316 stainless.

We'll need a few people to be interested for this to be a goer. Reason is the machinist will need to buy a non-standard M14 X 1.5 machine tap and an even more non-standard M14 X 1.5 left hand machine tap.

Making the centre tube in stainless steel possibly will not solve the problem, I expect you will get galvanic corrosion because the rod end and inner part of the arm are carbon steel and this will lead to contact corrosion.

Tom, when I freed mine up I drilled a small hole in the middle of the tube, in the top half. This meant I could get penetrating fluid inside as well as outside. Then it would boil up nicely once you heated em up a bit. It did free em up eventually.
I now make sure they get a squirt of oil every service just to keep em free. hth.

Tom,

Great idea, but have you seen that www.twosrus.com sells a pair of complete ends for $175? No idea whether the group buy you're intending would work out cheaper. I was intending to buy from twosrus - perhaps they might do us a group buy discount? Depends what price your machinist is asking - but I suppose you're only interested in the arms and not the ends??

Cheers

if anyone's interested.

I had a quote from Chris at cheaptoyotaparts.co.uk of £60 for just the tie rod ends, so it seemed sensible to get the lot for just a little extra, so when i get round to having an alignment, everything will be as tickety-boo as poss, as i'm having new ball joints all round too and have already done front tie ends.

I'm getting jokes at work about whether I expect my car to be "finished" by christmas. I think someone may even be running a book... :?
