after a fair bit of googling and some trial and error I've realised that the 4 links with a panhard will never work properly. Removing any of the links results in horrendous bump steer and is it stands a lot of the "spring" on one side is the panhard mount flexing with no damping which means getting reliable performance out of it is not going to be possible. I've seen some videos where people have fixed it with custom length links but I have neither the time or the interest to fix a bad original design replacing the servo mount with a 3d printed part and adding bracing across the shock towers is also a no go as both pieces are right next to the motor and would likely soften unless printed in something like ABS which I don't have access to going to put this truck on ebay before frustration with it drives me out of the hobby, I cannot stress how bad the plastics and design on this truck is

Mines still not happy, something is definitely binding as you can feel the flex in the panhard changing as you compress the suspension with no springs. I did some research and looked at my TRX4 and with a panhard 3 links instead of 4 seems normal, tried removing both top links one at a time and it was far too floppy and the axle moved in an arc instead of up and down. Its back together but still not right as I needed the work table free for something else. It still looks wonky when looked at from the front on so I'm wondering if I bent something else (servo mount is current suspect but its very hard to get at) Will have another crack at it when I've got an evening free before I start ordering parts

thanks for all the help, I've got some more pictures this is with no panhard bar attached, it seems to sit level this is with the panhard bar at the stock length, its definitely wonky this is with the panhard bar 3 turns longer than stock which looks okay but the panhard mount does a big old flex when you compress the suspension

Its weird, the rails were visibly pointing in one direction but now they are off they seem a lot better if still not identical. The whole front axle seemed to be off to one side with the shocks being at different angles which was why I initially thought I'd bent the panhard bar. Looking at it now its still slightly twisted so I'm assuming something is still not as it should be. Little bit wary of spending money on upgrades when I've already spent significantly more time fixing than driving it

Got myself an FTX Hi-Rock to drive for when I go crawling with mates (they get the TRX4) and it took a tumble down a bank. Worked out I'd bent/twisted the chassis rails so have spent the last few days switching everything over and discovering the difference between Traxxas and FTX plastics Its now less wonky but one shock still won't extend fully unless you pull on that end of the axle which then compresses the other shock. Shocks cycle nicely when they are not connected so I'm pretty sure the shafts are straight. I've tried figuring it out by compressing the suspension but I'm not having much luck as the shock towers both have a lot of flex in them, the panhard mount has several mm of movement and the servo mount also looks wonky and seems to have lost the panhard mount thread. I've had all the links off and they seem straight and have no differences left to right. The panhard bar has been swapped for a replacement as I thought I had damaged it but the new one has a threaded bit that has allowed me to bodge it but it still flexes the mount when the suspension compresses. Am I missing something with the setup or is it just a flexy piece of trash? And would any of the Alu upgrades be worthwhile, the servo mount is the single worst piece of design I've ever seen but is only available in plastic and the chassis has almost has much flex as the suspension so I'm inclined towards getting it fixed enough to sell and replace with something more durable (currently leaning towards a Gatekeeper kit)
