Dale Simpkins Posted January 22, 2006 Share Posted January 22, 2006 What year did LR introduce the Self-Levelling Strut on Range Rovers? I'm assuming that you're talking about the BOGE self levelling unit. These were fitted as standard with all Range Rovers from the launch of the Range Rover, so 1970.

Mean Green Posted January 22, 2006 Share Posted January 22, 2006 What are the effects of removing the Boge Unit? Quote Link to comment Share on other sites More sharing options...
bishbosh Posted January 23, 2006 Share Posted January 23, 2006 Suspension doesn't self-level . In reality, not a lot as by now most of them have failed anyway. If you carry heavy loads or tow a lot you might want to uprate your rear springs instead. Quote Link to comment Share on other sites More sharing options...
Diff Posted January 23, 2006 Share Posted January 23, 2006 What are the effects of removing the Boge Unit? As well as levelling the suspension(by pumping itself up to a preset point when driving down the road when loaded), the self levelling unit also assists the rear springs. So if you take it off, you will not only lose the self levelling ability, but you will also have very soft rear suspension(because you have lowered the overall spring rate). This may be too wallowy a ride on the road, and the back of the Rangie will sag with smallest of loads. The common fix for this is to fit heavy duty rear springs.

dollythelw Posted January 23, 2006 Share Posted January 23, 2006 measure the ride height, shove a few bags of cement in the boot, measure the ride height again (should be lower!), go for a drive and measure the ride height again (should be normal again) Quote Link to comment Share on other sites More sharing options...
Diff Posted January 23, 2006 Share Posted January 23, 2006 Is there any way of testing the BOGE unit to see if it still works? Yup, easiest is to drive around the block UNLADEN, bring RR to a gentle stop(so the back doesn't raise artificially) on level ground. Measure the distance between the bump stops and the rear axle and note it down. Then load the back of the RR with some REALLY HEAVY stuff, such that the back sags down. Measure the bump stop clearance again. Go for another drive araound the block, park up gently in the same spot and measure the bump stop clearance. It SHOULD have now pumped the back up so that the clearance is the same, or very close to the first unladen measurement you took, and certainly more that the second set of measurements. Don't measure bumper heights from the ground or similar, because it doesn't take into account any 'squashing' of the tyres with a full load.

Niall_CSK Posted February 2, 2006 Share Posted February 2, 2006 The Boge unit has a damping effect in addition to self levelling, it will tend to compensate for both weak springs and dampers. Easiest way to find out is disconnect it and go for a drive, you might be very surprised, I know I was . Without it you might need slightly heavier springs (as above) and heavy duty dampers if you want to maintain as near original handling as possible.
