Rear Crossmember Dimensions


Recommended Posts

Hi,

Does anybody have or know where I can find any design drawings of a standard rear crossmember.

There is a few dimensions on the chassis drawing in the workshop manual, but thats all I have found.

I plan on making my own rear crossmember for my college project and wanted some drawings as apose to going out and measuring my rusty crossmember which would not be very accurate.

This may turn into a winch ready crossmember, but haven't decided yet.

Thanks

Steve

Thanks Les.

I'm really after a design drawing from the factory, but I have not found anything on here or google etc. so I guess I'll have to make up my own.

Some useful dimensions would be:

- The overall length.

- The Height.

- The angle of the slanted edges where the mudflaps sit (on a 90), I'm guessing it's the same for a 110.

I think this would be a good basis to start with. As I am making my own, the only constraints I have is the slanted part where the mudflaps sit and the body work and so I guess it doesn't have to be exactly the same.

Are there any regulations that I need to worry about. I know of welding regs and so I will make sure that it is welded on securly. Lighting regs as I plan to relocate the fog lights into the rearcrossmember.

Thanks for your help Les

A DIY crossmember doesn't have to be anything like the original one - a lot of members on here have made their own from box section, u-section, etc. As long as it connects the ends of the chassis rails, supports the rear body, and isn't rotten, then that just about covers it :)

Can I just expand on what Les is saying - as long as the finished article resembles the LR one - i.e similar external dimensions then you should be OK, even if it has a winch tray let into it (c.f. Hybrid from hell's chat with VOSA / DVLA). However, you do need to tread carefuly outside of these parameters as strictly speaking you are modifying the chassis which takes you into the grey world of SVA. :ph34r::ph34r::ph34r::ph34r:

What I'm planning on doing is really to work in the confinments of the original dimensions and not go mad with wild designs! So from what your saying I should be fine.

Where is Hybrid from hell's chat with VOSA / DVLA? (I had a quick search and couldn't find it.)

My main aim is to make a crossmember that's strong and will not rust. It will probably be near to the standard shape of the original as it's going on my daily driver defender 90 that I use for pay and play days and maybe punch and winch challenges in the future!!

Hybrid's thread is the challenge wings SVA thread. He mentions within that how VOSA view cross member replacement.

My replacement cross member is a piece of 150 x 100 x 5 box with the ends tapered to match the original profile from LR.

I have drilled and tapped the bottom face for the tow bar mounts and tubed the holes through it for nato hitch etc. Details HERE
