Cougar SV pulling to left

[musicman]

Hi everyone

Has anyone got any advice as to curing a Cougar rear end from pulling to the left under braking and accelerating. I thought it was a loose Diff causing it, but I bought a built one to eliminate the issue, but still does it. Baring in mind it is fine on Astro, it's only an issue on low grip surfaces.

thanks

Have you checked weight balance left to right?

Check your shocks for equal Rebound and droop.
Also check for equal springs.Can happen that they are different on one axle.
Check for bent hingepins in/ outboard

Thanks for getting back so quickly. The Weight balance has been the same since I first got it, and for the first 5 months of running it, my cougar was great everywhere. All of the hinge pins are fine too, I check the car over after every meeting. I'm not too sure about the shocks, but when I rebuild them (every 2 meetings, I check they match each other. I might look into that a bit more.

It's the braking thing that baffles me, as I can understand the drive getting to one wheel more than the other when accelerating, as that's just the diff action with varying traction on either side, but I can't see why there would be more brake bias to one side to the other.

I come from a TC background so am happy to be told otherwise, however, the first thing I noticed when driving 2wd on a slippery surface was the unbalanced braking. All the 2wd cars I have driven have tended to pivot at the back when braking in a straight line. I guess the diff will work much the same way as it does under acceleration, when braking. One side is always going to have a slightly different level of grip to the other under braking therefore turning the back end as one wheel will be turning faster than the other. On high grip surfaces there's enough bite to stop the rear end from pivoting. That's my understanding of it anyway.

that sounds exactly like the problem I am having. It just seems strange that it's only in recent meetings that it's become an issue, and in terms of prepping the car, I haven't done anything different to usual...very odd
