Shudder at takeoff in 1st and reverse, 2000 Mazda B2500

Post by mjc85 »

My brother bought this car today, but he hasn't noticed it in the past few test drives before buying it.

But I have a bit more knowledge than him and if you let the clutch out at idle speed (approx 750rpm) or a bit above it has a bad shudder, if you rev it upto 1k+ then let the clutch out it's fine.

Does it in 1st and reverse, what could it be ?

Leaking rear main seal allowing oil to get onto the clutch?

I'm not sure, but possible as i know ford call there courier a b2500 as well. So you reckon just check the engine mount bolts and gearbox for tightness?

Not just the bolts for tightness, also check the rubber hasnt collapsed/cracked.

yeah the engine mounts are just rubber and generally crack. done quite a few at work. i would also check uni's, g-box mount rear axle mount bolts stuff like that before i pull the box out, stuff like that takes 2secs to check. remove and refit a g-box is a big job if you find nothing wrong with the clutch and the problem turns out to something simple

Check mounts, then look at clutch shudder.
