rockinroyston Posted September 16, 2017 Share Posted September 16, 2017 Had my 1000 mile bolt check completed & everything was fine apart from the tracking which they adjusted & there was a noticeable improvement (ive only done 400 miles in it lol the project manager had completed the other 600...).Had a quick look at the front suspension when I got back & one trakrod end has a lot of thread showing & the other one has none? Can this be right? I would have thought they would be identical? I know they started off as identical when I put it together as I had to take the suspension apart to do this...https://www.lotus7.club/blogs/return-front-suspension I'm not sure how to add a photo to this query so I'll put two up on my blogg /sites/default/files/images/users/39634/xlarge_2017-09-16%2008.51.01.jpg Link to comment Share on other sites More sharing options...

simon_h Posted September 16, 2017 Share Posted September 16, 2017 That's not the track rod end but rather the top wishbone ball joint. It adjusts the camber of the front suspension and possibly could end up different if the chassis isn't exactly equal side to side. I would expect them to be more even but I would ask what camber it's been set to. Link to comment Share on other sites More sharing options...
ScottR400D Posted September 16, 2017 Share Posted September 16, 2017 That's quite a difference. What camber is each side running? Are they a lot different? Link to comment Share on other sites More sharing options...
Jim 123 Posted September 16, 2017 Share Posted September 16, 2017 The Manual says for initial road use set up there should be 8 threads showing to protrude beyond the ball joint locknuts each side. Link to comment Share on other sites More sharing options...
elie boone Posted September 16, 2017 Share Posted September 16, 2017 it can be that one rod has more tread than the other especially if they are from a different manufactor, you need to measure the distance from the center of the rod to the locknut. first make sure the locknuts are the same thickness.

rockinroyston Posted September 16, 2017 Author Share Posted September 16, 2017 yes I set it to 8 threads & it came back looking like this (which I hadn't clocked until they mentioned the tracking was out when they did the 1000 mile bolt check. I'll take a measure from the centre of the rod to the locknut. I've no idea what the camber actually is as it was done by Caterham South behind closed doors.& sorry I meant wishbone ball joint, a picture paints a thousand words as Telly Savalas would say. I've also dropped Derek an e-mail to see what he thinks.. Link to comment Share on other sites More sharing options...
rockinroyston Posted September 16, 2017 Author Share Posted September 16, 2017 Well took a measure to it & looks like panic over... as suggested by Elie Boone i measured the distance between the Centre & the nut & they are both the same. Visually it looks different so I did it a couple of times (just because it still didn't look the same lol) with the same result! very bizarre & makes a bit of a mockery of the 8 turns on the thread guidance if the threads don't match on both sides.... Caterham must have disconnected & wound them inout as I cant see any other way they could have done it. Wasn't mentioned when it went for its post build check up.... I do recall it hardly managed it up the ramp when they picked it up for its PBC & had no sense of direction... I assumed it was just the tracking... must have been everything....

Jim 123 Posted September 16, 2017 Share Posted September 16, 2017 Whilst it's not over critical for road use, both wheels should be the same and with a spec of 1 degree 20 minutes negative camber that is pretty fine. Your photos imply it may be worth a bit of a cross check. It could just be chassis symmetry is needing to be accommodated at the ball joints.

rj Posted September 24, 2017 Share Posted September 24, 2017 Check and adjust tyre pressure. Find a flat space - center the steering wheel, put a carpenter's square next to the wheel and measure the distance from the rim to the square at top and bottom. If the difference is the same at both sides then camber is likely to be right.I would then start to investigate what is not straight though.
