Today's the day to find the problem with my bb4. Advice

So I've got my bb4 on the ramp, would add photos but I've not worked that out yet! The problem I have is when I pulled on the M1 last year, at 50mph she has gained a severe wobble In the stearing. At 1st I thought a lose wheel so checked nope. Also noticed when I stopped that she pulled hard to the left! So where do I start, what could be the cause? I've new upper control arms, new drop links, full poly bush kit and lower baljoints. I'd like to find what's wrong before I change everything as I may not have time to do it all before JAE. Any help is much appreciated.

Must add wobble stopped but still pulling to the left!

Id hazard a guess at the tracking
Was the tracking done after the parts were changed on the front?
Maybe also check the brake discs and calipers ? Maybe there is a warped disc? Should beable to tell from the noise if you jack the car up and manually turn the wheel
Also wheel wobble happens to me alot the wheel weights keep coming off mine must be my driving

I'd go for a binding caliper with warped disc causing the wobble. If you drive it, is the left front wheel/disc very hot when you stop?

I'd also agree with Gayno. Had a similar issues on my laguna. Drove fine but, must be when the brake got too hot, started a very severe wobble/vibrating. The next day it was fine until after 20 mins into the journey. Pulled over and could feel and smell the heat coming off the brake (was drivers side front). Replaced both front calipers and discs and pads and all was fine.

Your symptoms sound very similar to mine so that's where I'd check first

I did wonder if it was brakes but the wobble stopped and the discs are not very old. I've not altered anything g so tracking should be fine.

I'd still look at the brakes. Even if the discs are new, with a binding caliper will generate a lot of heat which can cause the disc to warp. You're not too far from me (Mildenhall) so if you get stuck, I can have a look for you

@ek9sid cheers that's good of you. So after not doing much, going out for a pub lunch I got back dropped the oil and fires her up. Took her down the street to free brakes as it's been sat since November. Brakes warm and she is not pulling to the left, brakes evenly! Problems don't just go away so what's happened there?!

think I'll take for mot and see what happens! !! Last time she burnt the alternator out during the test and I had to get towed the last mile home.

Try braking hard to get the piston out...that may replicate the binding caliper then

and no worries bud. I'm just a pm away

thought she was going to kill me when I last drove her but now I'm confused.!
