misalignment reducing spacers keep breaking

[Slowcoach]

Have yo thought about chrome moly. Might be a bit overkill and then the next weak link will need reworking, but if that doesn’t work it’s titanium next. (Don’t want to annoy you if you are a chef as I’ve seen “Delicatessen”)

What about going with HGV ball joint / TRE ?

 

[PhillipM]

they are going to vary the angle by quite a bit the front end has about 15cm of travel, maybe these are not the best things for the job, they are better suited to a stiff track car

Double check the angles and either use a larger joint with a bigger reducer spacer to get more angle, or make a bracket and turn the joint sideways if it'll do enough angle for the steering.

I have bigger problems now lol

What happened there ?

 

[Badger1bear]

Did ya axle drop too far and chew everything up ?

 

[123hotchef]

the front went airborne and that happened when it landed!

Go Big Or Go Home

i went home alright mate! haha had to winch out the place as i only had 2wd then 70 miles home she did well

next weekend is the re build!

I meant the faces of the spacers inside the joint. If you measure the joint width and the step on each spacer I’m fairly sure there will be a clearance and they do not touch each other as the spacers would have to be machined/ground to very close tolerances. I’m wondering if either the bolt compression is causing the relatively small lips to crush and fail or the spacers are tipping when the angle is exceeded.

and yoy mr @Wallace are the winner! i have not measured with the callipers yet but it is about a 8mm gap in between the top and bottom spacer so I will cut on of the old ones up and make a spacer then that should cure the problem. Why didnt I thin of that! it is always the simple things that are over looked

I was trying to think how to machine a pair of top hat spacers that touch inside the spherical rod end and tighten down on the outer faces, not an easy job unless you use a crush washer or leave a clearance and rely on the spacer lips compressing slightly when tightened. Maybe going up in size or two with the rod end would be a solution using the same bolt size.

I have tried that mate I drilled the tapered fitting out from m12 to m16 but the m16 spacers didn't offer as much movement as the m12 reducers.

Here we go

 

[Wallace]

I was thinking reducers and a even bigger joint with the same size bolt.

that would work but I think the ones I have been using will be more than up to the job with a spacer in between the top and bottom reducer

Sounds like it needs a redesign to reduce stress on the components

 

[PhillipM]

If you clamp the spacers together instead of taking the load through the ball, the joint will fret and move against the spacer surfaces.

I'd be checking your angles at full droop and full lock.

Well if 16 goes and it's M12 bolt atm:
