Knock braking / accelerating

Hello,

sorry cannot figure out how to post in the right area.

cannot get to the bottom of this

I have an r26 that has developed a knock, happens a little on the left but on the right it can be very loud and feels like something scudding under the right arch.

happens once each way accelerating once then braking once , won’t do same way twice. Sometimes it’ll bang multiple times when braking hard the one time. 3 quick bangs.

oem pads and discs
New pins
Callipers 175nm
New driveshaft
New driveshaft and bearing holder
New dampers . Springs all good ( eibach pros or something )
New tie rods and tre’s and tracked ( tracking still feels off )
Ball joints and wishbone bushes just done with new anti twist links

everything tightened very well including rack bolts

has a solid dogbone , new gearbox mount and engine mount also has polyurethane insert

gearbox was recently replaced and noise quietened for a few days

tightened everything underneath abd cannot figure it out

 

read that yeah, it didn’t seem to move when I done the tie rods the other week but looked shit

 

Done and done

Link to noise in reverse then braking

it’s sometimes quiet dull but can be pinging and high pitched and really loud, or can be very quiet

 

Checked the arb and stuff and seems fine

interestingly the wishbones were torqued on the axel stands with wheels hanging... is that a mistake , I’ve seen other posts also saying they need to be torqued at angle

 

Yeah think there’s 6

 

Hi everyone so... loosened the wishbones and tightened with the 3/4” bar which the wheels on the 4poster

no change to the noise
Also tried a larger bolt in the hole to fill the rear wishbone bush hole
No change
Took out cleaned and greased the rack bolts and no change

would the swivel bearings if they had went again cause a loud snapping noise ?
