Right then better start my '77 S1 project...

Recommended Posts

In defence of the poor old trunnion (who seems to be in for a lot of unfair stick IMO :lol: ), it is the upright that failed, not the trunnion. I thought the 'broken car picture' reminded me of a car cartoon with the front wheels at a rediculous angle! Must have been scary, but given it broke at the threaded bit, failure at low speed cornering makes perfect sense.

Poor maintenance (by the previous owners?, I can't accuse you Luke of poor work, given what you've achieved here!) has done it for the Panther on this occasion.

btw, really helpful photos above - be very interested to hear if you get anywhere with new replacement uprights - are these 'lotus specific' or were they GT6 as well?

Keep up the great work

Is the price for that bit in Yen or £?

Yeah agreed, the upright failed and not the trunnion and now I have something to compare it to, it was fk'ing knackered I mean the kit Dan supplied is literally as new, the threads of the uprights are as sharp as the day they were cut. Regarding the upright I left with the engineer, I'm still waiting to hear. However don't anybody fret, as on the way back I past lotusbits and they had a box full of new sparkling uprights sitting in the corner, so you could change for new if you need too. Yeah, I posted those photos with intent, I knew I'd be in line for a mauling but honestly, how many of you went straight out and checked your trunnions, a fair few I bet?! All good and we've all learned what not to do, should I have changed them in the first place, undoubtedly yes, but I have no regrets, Charlie and the Panther live on. Next up my vented brake disc conversion...

But the upright could have been stressed due to an historical poor trunnion issue.

just replace the lot and move onwards - could be worse - you could have been daft enough to sell a nice running car to buy a shed

Just like the 6 million dollar man, the panther is back, better, faster, stronger.

Never had any doubts that she would be gone for long Charlie, as with everyone else. We all look to see the next outcome of the Prowling Panther as everytime something goes, we know there will be an improvement of some kind will come out of the box.

Cheers JW, just been for a couple of shakedown tests, and I have to say my confidence has suffered a little, really didn't want to push her too hard, but after a few long straights and a couple of round-a-bouts all in all seems to be fine, tracking has moved slightly so a couple of turns needed to pull that back. What a week, glad that's out the way, running all over the place for parts, (massive thanks to Dan once again for hooking me up so quickly) and hard graft in the garage and we're back rolling again. All the best, Charlie ;-)

Great to hear you're back on the road. And these things can knock your confidence quite a bit; I've had a few of them myself with previous cars (front wheel coming off one car at 60-70ph on a motorway, bonnet flipping up on a shakedown drive at about 70mph, bringing the windscreen to about 6" from my face and denting the roof... you get the point!). You just get your confidence back through driving it and hopefully having problem free runs.

Got me thinking that this winter I'll try to overhaul the front suspension (trunions and bushes) and then I'll have done most of the front and back. Try to reduce the chances of the same thing happening to me.

Cheers lads, the encouragement will help for sure, I suppose it's much like a racing driver after an incident, get back in the car as soon as possible don't give the demons time to fester in your head. Honestly anyone who has a single doubt about the upright and trunnion on their car, GET THEM CHANGED and the only way to really check is by taking them off the car and inspecting them, I'll post a photo of my knackered upright, if your threads look anything like this, change it. Also oiling not greasing is the way to go, and actually very easy to do with a grease gun, clear the old grease from the canister, fill it with e80/90 and go as normal on your grease nipple, wait for it to flow over the top, very easy and satisfying to see them done. I've also changed antiroll bar bushes, greased the hell either side of the trunnion, make sure that moves with minimal drag and cleaned everywhere possible, calipers, pads the lot. Practically a new front end now, just have to keep telling myself, 'all new, all new'

Thanks, this is what happens if you don't look after your trunnions.

It's obvious that water has got past the seal and steadily eaten away at the thread weakening the upright, but without taking it all apart how can you tell before your flipping wheels fall off?! Joking aside, it's a serious problem and has knocked my confidence a bit so for anyone with doubt on theirs I would get them looked at straight away.

Epic pairing with the P1800 - love the styling of those as well. I looked at a Scimitar S5 before I plumbed for the Elite - it is amazing how close they all are in style but the Elite wins every time for me - it's like CC took the idea and just made it better! Actually didn't like the Scimitar when I sat in it but the guy who was selling it had an Éclat in his shed and let me have a look at that (not for sale and buried in a shed full of rusty classics - such a shame!). I was then sold on the Lotus!

Good work on the uprights - keep the faith, I know what the brain gremlins are like - especially when you do the work yourself but soon there will be nothing left that you haven't sorted :) :)

Cheers Ant, definitely getting my confidence back especially after a couple of long 2 hour runs, it's nice to know everything is now new upfront. That P1800 has just been featured in a well known web blogg, very cool car, mostly original and looks so cool in the flesh and that gold! Not much left to do with the Panther now, just keep it on the road maintenance.

Charlie. I know you will have something loitering somewhere ready to burst out. As for the P1800, craking car especially in Gold, suits it too the ground, as in real low.

The p1800 is very cool. You know what would compliment these two... a slammed Austin princess?

 Now there's a challenge Charlie. The Princess would be good as the wedge shape would suit it. Or go really radical and do a Princess 4Lt R.

It's been done before....

We popped a hydrolastic seal cresting a bump in the road outside Oban with the family's wildly overloaded sandglow beige 1.7HL Princess wedge.

eh voila: slammed Princess.... It still didn't quite manage to look like Harris Mann's initial radical styling sketches tho....

It just looked a bit shit. and it was beige. :ermm:

Someone on the Retro Rides forums is currently looking at modifying one, started asking me loads of questions on how to put it on air, sent me diagrams and everything. It could be done but would need a hell of a lot of fabrication as they don't use a spring in a conventional way, needes a pivotal system. Anyway I did this photoshop for him.

Didn't most Princesses end up looking like this anyway  :lol:

Those that didn't disintegrate into brown dust that is?

In their defence though, they were well ahead of their time and I have to admit quite liking them now :ermm: Imagine a 2 door version and you aren't a million miles away from the Eclat! :sofa:

Luke, just a quick question - how firm is the suspension when at the 'low' setting.

I can imagine getting in and denting the floor! 6'5" and 17 stone.............:angry:

60psi - drive height 1 - firm comfortable, no worries. 

50psi - drive height 2 - Slightly less firm comfortable, start to think.

40psi - drive height 3 - Still firm very comfortable, but eyes out.

30psi - drive height 4 - Less firm, ass starting to squeak a bit.

20psi - f'king low!

0psi - touchdown.
