Noises from front suspension/steering ?
Discussion
Any thoughts appreciated lads.
Protech Shocks,
Newish wishbones and all joints.
I live in road hump city and I have no choice but to use some pretty severe ones at that!
When the suspension is compressing as in when you first encounter the speed hump I'm getting noises,
I havnt looked yet so can't say more but it's almost like a broken Spring,
When turning tight st slow speed I get the odd sharpe clank and also a distinct tink, both sides are groaning as they load up, hmm not good.
I'll investigate at the weekend and see what I find!
Anybody else had noises from the front suspension and if so what was your particular prognosis,
Thanks Alun.

Drop link, I've been suspecting them,, similar sound Peter, cheers, I got lost there, thats a cool track you were playing with but I've never seen anyone using that layout,
Big slick and nice oversteer control, haha,
Crossmember,,I'll check that as I'd not even considered it.
Dave, I get your point entirely and forgive the car everyday but I've never had knocking / tapping noises before so somethings loose or worn.
By the way the Brembo's are a joy to use or what, are you happy with yours as I adore mine. They look ace but they work even better than that.
I'd been interested in a brake upgrade but hadn't got my head around what was needed, your thread made it clear and easy to make a decision, thanks man.

My old ones worked pretty good but my right leg was getting bigger 
other than what looks like caliper position my Brembo's are spot on,
It's added to the driving pleasure I think we both enjoy so much Dave,, just touching the brakes for a slight speed change is a king of quality event,
it's noticeable and I never fail to feel a warmth from it. Mad but with a car as fast as ours it's very comforting to know we have such fine braking potential.
I've been contemplating the thoughts above and I'm feeling slightly more relaxed, moving at speed it's pretty good and quiet, it is only these infernal speed humps that induce the crunching/ grinding/ knocking /banging,, f
king destroying my suspension stupid things,
My drop links I've noticed before are already looking decidedly useless,
I've been wondering if maybe the shock mounting bushes might have cracked but I've swung both shocks about and they feel secure, need to stop talking about it and get a proper look.

Removed left hand caliper and replaced upper ball joint then inspected my calipers, there fine, but my hub lugs that the caliper bolts to are slightly leaning out of line so as I have an extension bracket and 324 mm discs this gets magnified as you go further out from the wheel centre, this causes my caliper to be slightly out of alignment and the outside pad not biting as well as the rest,, can't do a lot about it unless I can find another hub to try!
Re assembled and bled brakes and they still feel sharpe and braking is pretty true oddly enough!

I hope so Ian, to be sure I bled lots of liquid through the system and the pedal feels solid and it does feel like the brakes are more balanced,
Replacing the upper ball joint has helped, was it brakes pulling or the wheel moving out of line as the joint was loose and I've brake tested with hands off the steering wheel and it's going straight,,
I need to do some big brake tests to see if that's cured a big vibration I was getting at Hethel the other week.
Nothing else seems out of place but I'm slightly worried about the front lower wishbone bush on the near side,
I might pull the lower wishbone off if the vibration remains.
So looking at the near side suspension everything looks good but the drop links shot so I'm assuming that's what's grating slightly over speed humps,
I had a right game getting the old ball joint separated from the hub, started damaging the puller so gave up and removed hub so I could knock it out with a drift,, kin elk, but it then came apart easily enough, hmm!
I also undid all the wishbone bolts and jacked the wishbones until level before nipping up bolts again, I wasn't sure if I'd remembered to do this when I put the wishbones on previously but they felt free in movement any way so that's another thing I'm now sure of.
Now for another test run.

N/S rear lower wishbone drop link mounting point,, so that's my pronounced tink when I go over speed humps or slowly up a curb then, kinda knew it was
Might get it repaired but as you can see it's really time I pulled this lot apart and tidied it up!
Drop links are about two years old.
Time for some proper ones rather than the chocolate O/E me thinks.
I'm pretty sure this happened at Hethel as I remember a loud crack as I went into the final right hander after the pit entry,
It was only a matter of time considering the rust!
Upside down,, obviously!

I can confirm I have a lower wishbone bush that's not sitting centrally, tight washer and a loose washer,, I put them in only two years ago and it's somehow moved, I've been thinking of trying poly bushes recently and this is only confirming my thoughts. It's all a bit fluid and doesn't offer much absortion anyway so I might chop the metalasic ones out and try something else.
Having pulled these things apart a few times now it's not such a head ache really and doesn't have to take that long either so I'll start looking into the poly bush route.
Oh, I used some motorcycle invisible stick like st to a blanket chain lube on all the bits that move, suspension bolts and bushes etc, a lot quieter,
Also did some shock adjustments,, it's took me months but I've finally found the sweet spot with my Protech shocks,
I'm running soft springs so quite a high bump setting to resist bouncing and 3 clicks less on the rebound,,
Fooking mega and really compliant and quiet. Get in.

I'm not sure about that now Rich, need to look again?
I'll get some drop links and then pull the shocks off to have a closer look over the next week or so.
I'll bell you as using the ramp would make life a bit easier mate, that old red one of yours must be playing up by now and need some labour
How is the car by the way,,,

I've sorted it,, removed ARB. nah, not really.
As you say Dave, your always going to get the odd knock and grumble with these cars, having looked at both front and rear ARB's there all displaying knackered drop links so the noises ain't alarming me quite so much now .
I've needlessly replaced the front wishbones as I have a full set of fronts lying about that I now think are perfectly OK,
I think I might get mine unrated rather than buy more of the same thing! ,,,,,,,,,,
Just ordered two of the stronger brackets so that's that then.
Cheers Dave you've saved me searching yet again

Just replaced my old front drop links with some from RaceTech,
I've been getting knocking / rattling / grinding when I go over bumps,
New drop links have silenced the suspension
Car feels taught and the drop links actually work now, cars more stable and less role into corners,
Very pleased.
Err forgot to take a pic off car so here's one with link fitted.

Alun, the standard drop links used by TVR are just like the ones on a Triumph TR6, their construction is a rubber ball vulcanised into an outer spherical metal socket, they were rubbish on the Triumph in the 1970's and just as bad today.
This type of crude vulcanised ball joint wears quickly and really has no place on a car likely to be subject to high cornering loads and one capable of over 150mph. Here's my six year old post when I removed my knackered original drop links and replaced them with with the excellent Leven rose jointed ones that remain on the car today and are still doing sterling service.

I'd seriously think about fitting the Leven drop links rather than the original vulcanised ball TR6 type that TVR used, I accept my originals were knackered but I certainly noticed a profound handling improvement from the Leven links and have proved they also last well too.
I'm confident you'll like them mate
I've recieved the strengthened plates for the rear wishbones that I'm going to use with these links Dave listed, This type of crude vulcanised ball joint wears quickly and really has no place on a car likely to be subject to high cornering loads and one capable of over 150mph.

I'm running the car with no rear ARB at the moment and it's not to bad to drive so I'll leave this job until nearer the winter,
Will,get wishbones re Furbed and powder coated at the same time etc so as the summers here I can't bare to take the car off the road
