1Gesus Posted December 17, 2014 Share Posted December 17, 2014 The ae85 panhard diff mount needs to be welded to the hilux diff. I will need to modify the mount (not much) to clear to the bigger diff center. What is the best angle for the bar to be on or should it be ideally be horizontal? The car will probably be quite low so i was thinking if im going to modify it, I could space the mounting point down on the diff to have the bar horizontal when lowered. Or go to the next level and make multiple mounting points at different heights... Am I on the right track? Quote Link to comment Share on other sites More sharing options...
flyingbrick Posted December 17, 2014 Share Posted December 17, 2014 As close to flat as possible. Nice setup! Quote Link to comment Share on other sites More sharing options...
kpr Posted December 17, 2014 Share Posted December 17, 2014 where its mounted affects roll center. could modify the bracket on the chassis with a range of holes, if you are going to take it on the track. then adjust to what works best Quote Link to comment Share on other sites More sharing options...
1Gesus Posted December 17, 2014 Author Share Posted December 17, 2014 yea definitely a track car. oh yea ill have a look into that Quote Link to comment Share on other sites More sharing options...
Celica RA45 Posted December 19, 2014 Share Posted December 19, 2014 roll center through the center line of the diff is your roll center .i have had 1 that is adjustable ,but its easier to play around with springs on the back if you lower the roll center at the back you need to do it at both ends . all this does when you lower it will make the back springs softer and make the car squat in take off but it will also make the car lift the rear wheels as well ,if the front springs are harder the faster you go through the corners with a low roll center will make the car lean more i ended up going back to the std roll center height to stop the rear from leaning over now with 235 lbs at rear and have 350 lbs in the front .this has made it sit flat going through turn 1 at the island 1 Quote Link to comment Share on other sites More sharing options...
spiderwebfx Posted December 19, 2014 Share Posted December 19, 2014 Sorry to jump in on this, but do 4-link set ups normally have a panhard rod? Or is it quite common to not have them? edit// nvm, mines triangulated, that's why i don't have one. Quote Link to comment Share on other sites More sharing options...
1Gesus Posted March 4, 2015 Author Share Posted March 4, 2015 if you lower the roll center at the back you need to do it at both ends . all this does when you lower it will make the back springs softer and make the car squat in take off I don't quite see how making the bar flat at a certain height will make the springs softer.. Anyway, got more serious issues. This diff isn't right. Who has a jig for ae85/6 rear diff mounts? Or who in nz is a pro at doing hilux diff into ae85 conversion? I need to get it checked and fixed. The lower rear shock mount is on a big angle and more so on one side. Which is the same mount that connects to the trailing arm Other side new shock wouldn't go on if i tried Quote Link to comment Share on other sites More sharing options...
Nominal Posted March 4, 2015 Share Posted March 4, 2015 What is you pinion angle like? If the whole axle is tilted back like that you will have bigger problems. If it is just the shock mounts then they can be cut off/rewelded to get them straight. Regarding the panhard rod, it should be level at ride height so the side-to-side movement is minimised. Moving the whole thing up and down will change the roll centre. Quote Link to comment Share on other sites More sharing options...
1Gesus Posted March 4, 2015 Author Share Posted March 4, 2015 pinion angle seems ok. but the shock mount is also one of the four link mounts. so any modifications will move the whole axle. seems like the whole thing needs re-doing unfortunately Quote Link to comment Share on other sites More sharing options...
kpr Posted March 4, 2015 Share Posted March 4, 2015 is that whole mount on the piss. or is the shock mount just bent? if you are good at measuring should be able to sort out whats wrong. the ones ive done i just measure up all the mounts. cbf with jigs, plus the factory stuff sometimes isn't that accurate anyway. check the diff case isn't bent also, you don't want to end up with a case with toe out or positive camber Quote Link to comment Share on other sites More sharing options...
Nominal Posted March 5, 2015 Share Posted March 5, 2015 It's just a pin for the shock, it can be removed and rewelded fairly easily if that is what's needed, without changing the whole mount. I suggest you get out a tape measure and level/protractor and work out if it is OK otherwise (centered/straight and pinion angle the same as the engine). Another option would be making the top links adjustable to change the angle of things. 1 Quote Link to comment Share on other sites More sharing options...
kpr Posted March 6, 2015 Share Posted March 6, 2015 Kinda looks like whole mount is welded on wrong, Quote Link to comment Share on other sites More sharing options...
1Gesus Posted March 9, 2015 Author Share Posted March 9, 2015 yea seems like it is welded on wrong. but if it was way out it would be hard to bolt the link to it, assuming the other mounts are in the correct position. But the diff goes in pretty easy. I'm trying to line up another standard diff to compare against. probably a ke70 one. pretty sure there the same Quote Link to comment Share on other sites More sharing options...
