Boxsum Posted April 15, 2021 Report Share Posted April 15, 2021 Hi how do you remove the rear toe arm bolt out as it hits the cat? Don’t really want to start fiddling with the exhaust if possible Thankyou Link to comment Share on other sites More sharing options...

Don’t really want to start fiddling with the exhaust if possible Thankyou I remember having this problem. Its hitting the heatshield so you just need to remove that and then you can wriggle the bolt past...theres a screw and retaining clip on the top of the cat if I remember correctly.

½cwt Posted April 15, 2021 Report Share Posted April 15, 2021 As I had to cut mine I didn't have a problem getting it out but getting back in I did with the toe link disconnected front the hub too so you can use the angle of the slotted hole to line up in the bush a bit before it is fully squared up. Certainly didn't have to remove a cat although I might have been helped a little by not having heatshields fitted. Link to comment Share on other sites More sharing options...
Boxsum Posted April 15, 2021 Author Report Share Posted April 15, 2021 All done Thankyou I just had to loosen the 3 bolts where the cat pipes join the manifolds to gain access to remove the bolts. Think I was extremely lucky as all the bolts undone quite easily and all looked great condition so I could reuse. Just need to get tracking checked Link to comment Share on other sites More sharing options...

That is not the correct bolt! Some Herbert has used a wishbone eccentric bolt which is longer Link to comment Share on other sites More sharing options...

I do have euro cup headers fitted if that makes a difference to where the cats may sit? Just back from 4 wheel alignment and drives beautifully. Would definitely recommend a front/rear suspension refresh👍 Link to comment Share on other sites More sharing options...

Probably fitted in 1998 in South West Germany😉 Link to comment Share on other sites More sharing options...
Boxsum Posted April 15, 2021 Author Report Share Posted April 15, 2021 Like I said I’ve changed my headers so this may explain it but mine were definitely original bolts. Link to comment Share on other sites More sharing options...

TROOPER88 Posted April 15, 2021 Report Share Posted April 15, 2021 In that picture, it is most certainly the wrong bolt. It is hitting the cat and the threads are not even clear of the casting. I have done so many of these that I have lost count. You most certainly do not have to remove any exhaust components to remove them. I have one booked in for Sat, I can picture it.

If the bolt was shorter then the nut would have no thread to connect to the other side when inserted ? Are you sure changing the headers wouldn’t move the cats slightly forward Link to comment Share on other sites More sharing options...

It is not that short! It will clear the cat though. The wishbone eccentric bolts are slightly longer. Tbh, I have seen it a few times Link to comment Share on other sites More sharing options...

Boxsum Posted April 15, 2021 Author Report Share Posted April 15, 2021 After changing the six components this is how far the rear tracking was out. Not sure if it was even worth re-tracking but I don’t really understand the parameters. Link to comment Share on other sites More sharing options...

Tbh would the thread even be cut long enough for the bolt to tighten against the upright. Link to comment Share on other sites More sharing options...
½cwt Posted April 15, 2021 Report Share Posted April 15, 2021 Toe link bolt is 83mm (and about two turns of thread through on mine), coffin arm bolt 100mm (and about half a turn through on mine). Headers might explain it. Link to comment Share on other sites More sharing options...

Not sure if it was even worth re-tracking but I don’t really understand the parameters. The back end should feel more stable now with the correct toe settings. Should improve rear tyre wear too.

Maybe it is just the pictures but it looks like a lot of old oil on your cam cover. Could be a few things tbh Have you cleaned it off? If not, G101 with a paint brush and then keep an eye on it but most likely is the plug tubes 👍 Link to comment Share on other sites More sharing options...

The suspension was giving more than enough grief at the time I took these pics to worry too much about cleaning cam covers. First time round on a Boxster rear suspension rebuild an everything was seized, all 4 eccentric bolts and both drop links, you can even see the induction heater coil and the remains of an eccentric bolt in the first pic... May be next time I'm under there, I've got a painting kit for calipers and a brake pipe kit too but the weather will need to warm up first.

Must be the headers that move the cats slightly forward. It did feel a whole lot better done 👍 BTW the tuning fork bolt wasn’t that hard to get to either so well worth it , my bushes were quite pliable but not totally knackered Link to comment Share on other sites More sharing options...

Can be a pain with seized. I am currently working on one and need to split the cats from the manifolds!! Link to comment Share on other sites More sharing options...
