Can anyone tell me why the passenger-side bump stop in the live-axle 100 series is so much longer than the driver's side one? Thanks, Casper

Front or rear ?

I removed the rear ones to fit poly bags and they were the same length.

Sorry, front ones. Yes the rear ones are both the same length.

Just guessing but would probably have to do with the diff being closer to one side

Just had a look at my neighbours 100 series and the bump stops are of equal length both front and rear.

Yes maybe it's because of the diff? So that the axle travel is about the same on left and right so when you bottom it out it bounces back straight?

In practise the passenger-side is a bit closer to the axle housing and seems to be the only one that hits regularly - going by the fact that the axle housing always has a nice clean rectangle on the left under the bump stop but that under the right one the axle housing is always dusty. Maybe too the extra weight of diff + drive shaft on the right means that it doesn't fly up as far generally?

I've really no idea, and going a bit fast on the rough means that the suspension bottoms out occasionally, and on the left only mostly. I'm expecting to drop the front springs soon anyway so I suppose if it doesn't look like anything interferes I can try putting a short one on the left too and see how it goes...along with a little extra lift.

Mine are both the same length as well. Sure it ain't busted?

Its because of the thickness of the diff where it contacts....

I went out to the garage and looked first. Both front bump stops are the same length and the gaps between the bump stops and the axle is the same both sides too. 2003 standard 100 series. Maybe something is missing on yours?

Thanks guys. At first I thought it was because of the shape of the diff, until I measured the distance to the axle and found that it differed by the length of the bump stops, ie the travel would be the same if the bump stops were the same...yes measured eyebrow height to check the car was level first...

Seeing as others have them both the same length I'm thinking one of them might be a replacement, although I peeked under another car in the car park the other day and it was set up the same as mine! Mine's a 1999, maybe things have changed. I'll do some more "research" in the Toyota dealership next to work, then get another shortie and see how it goes.

Thanks again, Casper.
