Having run my mr2 through the winter without a problem, recently it has developed a really annoying knocking noise at low speed 5-20mph over slightly rough ground. I have had the front end up on axle stands and given the wheels a good shake and turns to see if anything happens, but nothing. Any suggestions?
You might laugh at this but the exact same thing happend to me then I removed my front bumper the other day and much to my suprise
My horn was banging on mt front bumper support after months of trying to find this annoying knock it was that lol
It could be anything. Droplink/ARB bushes/Top mounts/Loose bolt/Worn arm bushes.
From experience, i've had my topmounts knock over slower speeds. If you can't find the source, it's probably them
On mine it was the front anti roll bar drop links as suggested earlier, get under the car and give each drop link a good tug, if there's movement there's your culprit.
