right i bought some 172 brakes off crossers the other week, fitted them and bled them, and all was good, ive noticed that with the 172 hubs, the track is slightly wider, took it out for a spin to check all was ok, came to a corner of my private test track which has a slight rise/camber, as the car went over it while turning the n/s driveshaft popped out of the gearbox. im thinking the shafts are a tad too short now?? or do they tend to pop shafts often?

think the shaft only wants to be a tiny bit longer i recon and i have a few n/s shafts i could butcher to make a longer one but im not sure how much longer it'd need to be

would 172 shafts fit?
how much longer are williams shafts or 19 16v shafts?

any more ideas anyone??

i *think* one of the R19 16v shafts is longer... i thought it was the O/S though

ill look into that

im not sure how much longer i need the shaft to be yet as it may have been a one off thing that it popped out, not drove it since

could do with crossers replying see if it happened to him much

damn edit button,

at a guess id say it was the n/s one that was longer on a 19 as the engine bay is bigger but the top engine mount is the same as a clio iirc


anyone else, any ideas?

The 19 16v dont have any top mounts there all bottom mounted just if you didnt know

nar its deffo the shaft, going to have it apart in the moring to have a look, might have broke the shaft tbh.

if it was the diff circlip wouldnt i lose drive?

yes you would...

teabag

yes you would...

deffo not the circlip then as i popped the shaft back in reversed off my drive and i came out again, im thinking ive broke the end of the driveshaft now. it did go with quite a bang with it went.

would the 172 hubs mean id need longer shafts?
im noww thinking it wouldnt :?

off to a breakers in doncaster tomorrow as theyve got a 17poo in atm

all it needs is a slightly longer shaft by the looks of it, im thinking a williams shaft might sort it

I got no problems with my 172 brakes, I'm driving a R19 16v though, they have a wider track... You can use those shafts to I think...

camber seems ok tbh think its because its fited with williams shocks

and its not the wide track that im after its the bigger brakes

ive got a n/s 172 shaft im gunna fit today think that should sort the popping out

how much longer is a n/s R19 shaft compared to a valver n/s shaft?

if you had wiliams shocks on then i'd say your camber would be stupidly positive!

i know your not after widetrack but you would not regret doing it and then everything would match up too instead on havin godd driveshafts! (i know they are odd as std but they are matched as a pair).

yea i know what u mean...one 17.2 shaft and one valver shaft

think ill have to dip my hand in my pocket again soon then lol


would camber correcting bolts sort it in the mean time?

grrrrr bloody renault

cant get the cv off the 172 shaft looks like its a solid peice at the end instead of splines and a circlip like on a valver cv

2 options now.....

go back to valver brakes which i dont want to do

or

try a 19 16v shaft or a willy one.

how much longer is the 19 16v shaft compared to a clio valver one?
