Hey have been trying to convert a few cars from fwd to awd. The same problem occurs, the front wheels spin atleast twice as fast as the rear and explodes.. How can I fix this?
Is the car high powered? It could be something to do with the type of differential being used. If you have an open center diff, similiar to how an open rear diff works but instead of the wieght shifting left or right making the inside wheel spin. It could be the front ones spinning as all the wieght has shifted to the rear making the rears much harder to spin which causes the fronts to instead. Just my 2 cents.
which cars are you having issues with mate? I ran into the issue once before, in hindsight I think it had something to do with the way I had the transfer case connected to the differentials, it might pay to check that you are on the correct outputs from the transfer case, just in case both front and rear shafts or differentials are tied to a single output
Hey thx for answer it is the Ibishu Covet this time. I have copied the race front diff and changed it to "hatch_differential_R" so front and rear is exaclty the same, also adding this too one of the gearboxes. When driving in high gear low revs front wheels doesnt slip, only when highpowered start the wheels spin all the way up to over 350km/h (even in low gear) and then explode. It might have something to do with the center diff? This is what I copied right after front race diff, basicaly changed all to R.

I have the same issue, even with a transfer case, but I deleted that because it didnt help To solve this issue during gameplay, make sure you dont give full throttle and keep your front wheels on the ground when accelerating. my code: --- Post updated --- perhaps @Diamondback or @synsol could help ?
My Legran mod did this. It was going to be AWD. But at the last second I changed it to RWD, because it didn't have that problem.
When I only select the rear diff, it works like expected, but a rally covet and rwd=disaster^100 So I want it to be AWD or 4wd (doesn't matter for me) UPDATE: with some help from flying to your soul, we noticed that only the front wheels are driven and it bugs out, so I am trying again now by looking at the pessima code since that is a fwd car too with optional rwd stay tuned.
I got it working If you add a transfercase, make sure that your input on the diffs is "transfercase" and 1 for the rear diff and 2 for the front diff
How? can you copy the text here. I am getting nowhere been trying to copy most from sunburst but it just turns too shit..
Will do it this evening, you can't just copy it since it is for my AWD mid engined rally covet , see development screenshots for pics
I posted an awd covet in mod help a few weeks ago. It's a 5-10 minute job. Add a differential to the transmission jbeam with its input set to be gearbox. Change front diff to take the centre diff index 1 as it's input, set rear diff to take centre diff index 2 as it's input.
After I figured it out it was indeed . But you need to know that the front diff has as input transfercase, 2 and the rear diff transfercase,1 that is all. --- Post updated --- Spoiler: code, edited so you can't copy my project...

I know it's already been answered with a solution, but I just did an AWD conversion on the Pessima by copying the drivetrain setup from the Sunburst. You'll need to add a driveshaft that takes input from a rear differential and transfers it to a transfer case. The transfer case is then responsible for transferring the power from whatever differential setup you have into the gearbox, where it is transferred to the engine. In addition, the front differential will have to output to the transfer case instead of the gearbox. To re-cap: Engine -> Gearbox -> Transfer Case -> Driveshaft -> Rear Differential, change front differential to output to the transfer case instead of the gearbox. Look at the sunburst files (engine and rear suspension jbeam has everything you need to convert FWD to RWD/AWD)
