benje 0 Posted June 22, 2008 Ok, I'm after some replacment bolts and nuts for my balljoint clamp on the 306. Now before I go and pay peugeot £4 for 2 bolts and 2 nuts is there an easy way to decipher the information from the service box? Peugeot state the bolt is: 10x150-50 and the nut is : 10x150-12 6-16 Right, so am I right in thinking this is nothing more than a M10 x 50mm? Whats the 150 there for? Thanks all Ben Share this post Link to post Share on other sites
Ryan 99 Posted June 22, 2008 M10x50mm is correct. 150 is the thread pitch - 1.5mm. Share this post Link to post Share on other sites

Tom Fenton 1,536 Posted June 22, 2008 Not as simple as that, it needs to be a BOLT with a plain shank for part of the length. If you fit a SET SCREW (fully threaded) you will find you have play in the balljoint again in no time. Share this post Link to post Share on other sites
welshpug 1,649 Posted June 22, 2008 also make sure they are High Tensile Steel, grade 8.8 minimum, and don't over-tighten them Share this post Link to post Share on other sites
Jrod 7 Posted June 22, 2008 I ordered brand new wishbone bolts from Pug the other day and they are totally the treaded, I decided to reuse the old ones but a bit off coming from the dealer! Share this post Link to post Share on other sites
welshpug 1,649 Posted June 22, 2008 that's apparently quite Common, I got some recently that were correct though. Share this post Link to post Share on other sites

I've also had the same thing in the wishbone bush kit, with set screws supplied for the inner bush pivots. I re used the old proper bolts. Share this post Link to post Share on other sites
benje 0 Posted June 22, 2008 I'll probably end up getting some stainless ones off the web. The left hand one was slightly bent :o so it definately needs replacing. While we are on the topic of wishbones if anyone is still reading. I've replaced them both as the rear bushes were completely shot, i.e the wishbone had about an inch of movement in the bush at the back Only thing is, the left one now seems to crack when pulling off. Have I over torqued something somewhere? Or would the knackered wishbone have destroyed something else, and new wishbones are highlighting the issue?

Tom Fenton 1,536 Posted June 22, 2008 First off all DO NOT use a stainless bolt, they are no way near as strong as a proper high tensile steel bolt, basically NOT suitable for this application. When you replaced the wishbones did you put the car on its wheels before tightening up the wishbone bolts? If not this could be your problem. Share this post Link to post Share on other sites
jackherer 543 Posted June 22, 2008 Only thing is, the left one now seems to crack when pulling off. If you can't find any play in the wishbones check the subframe bolts are correctly torqued. Share this post Link to post Share on other sites
benje 0 Posted June 23, 2008 Yeah i lowered the car and tightened them on the ground to the specified torque. I think i'll have another go this weekend. Although one thing i did notice is that there was still a bit of play in the wheel holding it at 9 and 3 o'clock, and pulling it and pushing it towards me. I can only assume it's killed the track rod end also. Which kind of makes of sense as the movement of the knackered wishbone was being transmitted back through the rack to the steering wheel. Thanks for the tip on the bolts i'll get some high tensile jobs then. Ben. Share this post Link to post Share on other sites
