After driving on pavement 27 miles up the mountain to 4K feet then down 14 miles the most traveled N/S I-5 hwy in California, USA. Hr & 1/2 between each 5/101/1 for the most part flat, less curves thus quicker by hour or more N/S route. Traveled this route numerous times especially to/from the Pacific NW once a year the past 20+
With the huge amount of heavy loaded 18 wheel rigs transporting goods via I-5 add double trailer loads of tomatoes, carrots, cabbage, grapes nuts depending on season 24/7 as 1/2 of all USA produce grown in Central Valley 400+ mile stretch Bakersfield to Redding you get a beat up 2 lane hwy, 1 lane maybe shut down for 12 miles during repavement, in stretches, though the road looks smooth, slow lane teeth chattering bumpy, forces you to drive in fast lane. Not an engineer what attributes to the road wear, it's dry desert, rarely rains, extremely hot at times 100+ degrees, when it does rain slight slop of the road drains water towards right shoulder, though mostly paved 50 ft patches of concrete repairs are done under the many of the overpasses I-5
Suggestion:
You on I-5 get in left vs right lane before overpasses, caution fast lane can be beat up as well, I've seen big rigs bumper to bumper 4 deep both lanes, as traffic moves 85-90+mph as it's out in the open tracked by air for speeders & often no space to get over so you're trapped in right lane, driving over, not your simple potholes but 2-4+" depressions of broken concrete slabs. In hindsight during latest trip did see at least 3 modern vehicles alongside the road at varible strectchs after an overpass with flashers on 1st thought, electrical, out of gas, may've been results of driving over these depressions
My 3042 mile roundtrip travel to the Pacific NW we encountered several of these patches, as previously posted destroyed the superpro bushings on rear shocks, out of the 2 top/2 bottom, the insides bushings on rears were gone plus the washer on driver's side concaved, result of hitting these depressions @70 mph, could see them, but not able to change lanes due to fast approaching traffic on my left, couple times drove to right where only left side tires hit the depression, results Bam! as though I hit a concrete stop in parking lot happened at least 4 times hardest impact ever in my TR6 made me cuss out loud.
Went for 4 wheel alignment same place 2 months prior, took box of shims (1/16-1/8-3/8"
to help with 1 size shim from vendors. With the shims & G.P. adjustable trailing arm brackets the rears dialed in -camber. The fronts couldn't be aligned, shop was puzzled, called me into the pit, we looked at the upper/lower trailing arms & entire front suspension parts (nuts, bolts, washers, poly bushings) all seemed fine said he heard a pop when raising TR while on rack to align but couldn't duplicate sound while I was in the pit.
Drove home called Master British Mechanic Tracy said he'd be by @3pm got off the phone to the TR6 Cave while wheels on the ground full front end suspension inspected, further inspection above removable suspension parts passenger side looked normal, driver's side my TR6 directed my view above front suspension, where I could see torn sheet metal.
Tracy & I put eyeballs on the suspension told him I was searching to order suspension parts but can see an immediate problem. Jacked up the front end, removed the tire, there it was in plain sight, horizontal crack on sheet metal & broken weld where it's welded to shock tower (must've been what alignment shop heard pop) causing right front tire to lean in at the top
Called shop that did 2016 respray as funny car racers very detailed/precise in repairs, fact they used machine grade brass bolts as well as put my TR6 on frame aligned/shimmed body where needed though not part of respray just what they do RIGHT.
Explained hit several major depressions @70 mph, broken/missing shock bushings. Told earliest they can do repair 3 wks looking at pics said they's beef up that sheet metal, thorough inspection entire frame
Good thing I got in 3042 miles of seat time over 11 days as we'll be out of commission for Nov & part of Dec Love My TR6 got me there & home!
